  COMMAND: "<message>

  Says <message> out loud to everyone in your current location (usually a
  room).

  Example:
    > "Where is the movie theater?
    You say, "Where is the movie theater?"

  Note that the closing double quote is automatically added.

  Related Topics: page, pose, say, :, ".

& #
#

  COMMAND: #<number> <command>

  Forces the object whose database number is <number> to perform <command>.
  Example: '#1033 move north' forces object #1033 to go north (assuming that
  you control it).  The same restrictions that apply to @force also apply to
  this command.

  Related Topics: @force.

& $-COMMANDS
$-COMMANDS

  These commands are called arbitrary commands, user-defined commands, or
  $-commands (for how they are defined).  See 'arbitrary commands' for the
  full description.

  Related Topics: arbitrary commands

  COMMAND: &<attribute> <object>[=<value>]
  SYNONYM: @set <object> = <attribute>:[<value>]

  Sets the attribute named <attribute> on <object> to <value>.  If
  <attribute> is not a predefined attribute (like ofail or va), then it is
  created.  Attributes so created are called user-named attributes.
  Attribute names may only contain letters, numbers, and the characters
  < -_.@#$^&*~?=+| >, and must start with a letter.  The names of user-named
  attributes may not be abbreviated (an attempt to get the value of the
  attribute will fail, and an attempt to set will create a new attribute).
  The & command may be used to set predefined attributes (in this instance,
  '&<attr> <object>=<value>' is equivalent to '@<attr> <object>=<value>').

  Related Topics: @set.

& :
:

  COMMAND: :<message>

  Displays <message> to everyone in your current room, preceded by your name
  and a space.

  Example:
    >:jumps for joy.
    Player jumps for joy.

  Related Topics: page, pose, say, whisper, ;, ".

& ;
;

  COMMAND: ;<message>

  This command is much like the ':' command, except that no space is inserted
  between your name and the action. 
 
  Example:
    > ;'s watch beeps.
    Player's watch beeps.

  Warning: This command does not work in command lists run from an attribute
  because the ';' is treated as the command separator.  Use pose/nospace
  instead.

  Related Topics: page, pose, say, whisper, :, ".

& @@
@@

  COMMAND: @@ <args>

  This command and everything after it (excluding the command-separator
  ';') is not evaluated by the parser. This is useful for adding comments
  in softcode or, more commonly, writing comment headers for softcode
  installers (such as /quotable text files).  Note that @@ must be
  followed by a space or it will return an error message.

  Always be doubly sure that ()'s and {}'s in the (otherwise ignored)
  arguments are nested correctly, so that any semicolons used to separate it
  from subsequent code in the line are recognized by the parser.

  Example:
     > @va me=$foobar *:@fo #1234=%0;@@ This controls my foobar puppet.
     > foobar say Hello World!
     foobar says "Hello World!"
     > @@ --- Begin Code ---
     > @emit Hello World!
     > @@ --- End Code ---
     Hello World!

  Related Topics: think, @@(), null().

& @@()
@@()

  FUNCTION: @@(<text>)

  The <text> is not evaluated and returns nothing.

  Example:
    > think @@(pemit(me,Hello))
    > think @@(abc)

  Related Topics: @@, null().

& @AAHEAR
@AAHEAR

  COMMAND:   @aahear <object> = <command-list>
  ATTRIBUTE: Aahear

  An Aahear on an object is activated whenever the listen pattern
  matches anything done/said by anything else in the room, including
  itself.  (The Ahear ignores itself, helpful for keeping machines from
  triggering itself)

  Example:
    @aahear listener = "I heard someone (maybe me?) say the word!

& @ACLONE
@ACLONE

  COMMAND:   @aclone <object> = <command-list>
  ATTRIBUTE: Aclone

  Sets the actions to be taken by a new object that has just been created
  as the result of a @clone command.  The contents of the Aclone attribute
  are run by the new object and not by the old object.

  This attribute is only meaningful for things, and will never be
  automatically triggered on other object types.
  It is also possible to check the zone object/objects in the zone parent
  room for an @adisconnect. If one is found, it will be executed when a
  player disconnects in that zone.

  Example: @aclone Time bomb = @wait 600=@trig me/va;@wait 10=@trig me/vb
           @va time bomb = :EXPLODES with a thundering roar;@destroy me
           @vb time bomb = :ticks.; @wait 10=@trig me/vb

      because they fail the object's default lock.
    - For rooms, players, and things: Someone looks around inside the room,
      player, or thing and fails the object's default lock.

  Example:

  Provides an alternate name by which the player is known.  The alternate
  name is only used for players when referenced as '*<name>' or by commands
  that only take playernames (such as page or @stats).  You may not set
  an alias on any other object type.

  When setting an alias, the alias is checked to see that it is both a legal
  player name and not already in use.  Only if both checks succeed is the
  alias set.

Related Topics: @name.

& @AMAIL
@AMAIL

  COMMAND:   @amail <player> = <command-list>
  ATTRIBUTE: Amail

  Sets the actions to be taken after a player receives @mail. This should
  *never* @mail another player, as this could cause an infinite loop.

& @APAY
@APAY

  COMMAND:   @apay <object> = <command-list>
  ATTRIBUTE: Apay

  Sets the actions to be taken after the object is given the number of coins
  specified in its Cost attribute.  If the giver tries to give more than that
  number of coins, the excess is refunded, and if less than the necessary
  amount is given then it is all given back and a snide message is sent to
  the giver.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Example: @apay Coke machine = @clone Can of Coke; :drops a can on the

  Related Topics: @otport, @oxtport, @tport, @teleport.

& @AUFAIL
@AUFAIL

  COMMAND:   @aufail <object> = <command-list>
  ATTRIBUTE: Aufail

  Sets the list of commands to be run when someone 'use's the object but
  fails the object's use lock.  Note that the other functions controlled
  by the use lock (paying, listening, and $-commands) do not trigger
  Aufail.

  Example: @aufail robot = "I _told_ you to leave me alone; kill %n=100

  Related Topics: @oufail, @ufail, @use.

& @AUSE
@AUSE

  COMMAND:   @ause <object> = <command-list>
  ATTRIBUTE: Ause

  Sets the actions to be taken when someone uses the object with the use
  command.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  This attribute is sent as a message to anyone who tries to page you when
  you are not connected.

  This attribute is only meaningful for players, and will never be
  automatically referenced on other object types.

  Example: @away me = Hey, I'm not even connected.  So why are you paging me?

  Related Topics: @idle, @idletimeout, @reject, page.

& @BREAK
@BREAK

  COMMAND: @break <boolean>

  @break stops the execution of further commands in the current action
  list if its argument is a true value. It doesn't affect new queue
  entries made by previous commands in the action list. Very useful to
  people who don't like @switch.

  Examples:
    > @va obj=$testme *:@pemit %#=Before;@break %0;@pemit %#=After
    > testme 0
    Before
    After
    > testme 1
    Before

    > @force me={@switch 1=1,think 3rd;think 1st;@break 1;think 2nd}
    1st
    3rd

  In the last example, the @switch is run, which queues 'think 3rd',
  'think 1st' is run, displaying '1st', command execution is broken
  (so we never 'think 2nd', and then the queued 'think 3rd' is run,
  displaying '3rd'.

  If you follow that, you have a very good understanding of the
  TinyMUX queue. :)

& @CBOOT
@CBOOT

  COMMAND: @cboot <channel>=<object>

  Only wizards or the owner of the channel can use this command. It
  forcefully removes an object from that channel.

  You may specify a player name as <object> if you prefix it with an '*'
  (e.g., '*Player1'), otherwise <object> should be a dbref or if you are
  in the same room, the name of an object or player.

  Example:
    > @cboot Public=Player1
    [Public] Staff1 boots Player1 off the channel.
    [Public] Player1 has left this channel.

  Related Topics: comsys commands

& @CCHARGE
@CCHARGE

  COMMAND: @ccharge <channel>=<amount>

  This command imposes a charge of <amount> coins on transmitting over a
  channel. The default fee when a channel is created is 0. All proceeds
  benefit the channel owner.

  Example:
    > @ccharge Public=1
    Set.

  Related Topics: comsys commands

& @CCHOWN
@CCHOWN

  COMMAND: @cchown <channel>=<player>

  Changes ownership of <channel> to <player>. If the player is not in the
  same room, you will need to add a '*' before the name (e.g., '*player1').

  Example:
    >@cchown Public=Staff1
    Set.

  Related Topics: @clist, @cwho.

& @CCREATE
@CCREATE

  COMMAND: @ccreate <channel name>

  Only Wizards can create new channels.

  Creates a new channel with default settings. Once the channel is created,
  it can be associated with a object with the @cset command. That object can
  be used to set locks and descriptions on the channel.

  Example:
    > @ccreate Public
    Channel Public created.

  Related Topics: comsys, @cset, @cdestroy, @clist, @cchown.

& @CDESTROY
@CDESTROY

  COMMAND: @cdestroy <channel>

  Deletes <channel> permanently from the comsystem database. It does not
  destroy all aliases that exist for <channel> -- those are left to the
  owners of those aliases. Players are notified both at login when they   
  own aliases for which a channel no longer exists and when they try to 
  use them. Even if a Channel is destroyed and then recreated, the alias 
  will still be non functioning. The alias must be removed with the 
  'delcom' command and added with the 'addcom' command.

  Example:
    > @cdestroy Staff
    Channel Staff destroyed.

  Related Topics: @clist, @ccreate, @cchown, addcom, delcom.

& @CEMIT
@CEMIT

  COMMAND: @cemit[/<switches>] <channel>=<message>

  Sends <message> over <channel> prefixed by the channel's name. You must own
  or control the channel to do this.

  The following switches are available:

    /noheader - Sends the message to everyone on <channel> without the
                channel's name prefixed.

  Example:
    > @cemit Public=This is a test!
    [Public] This is a test!

    > @cemit/noheader Public=This is a test!
    This is a test.

  Related Topics: comsys commands, alias, addcom.

& @CHARGES
@CHARGES

  COMMAND:   @charges <object> = <count>
  ATTRIBUTE: Charges

  This attribute allows you to limit the number of times an object can be
  used.  If there is a charges attribute it is decremented each time an
  action on the object is triggered.  Once it reaches zero, normal triggering
  stops and the Runout attribute (if one is present) is run instead.

  Example: @charges Fireball wand = 5

  Related Topics: @runout.

& @CHOWN
@CHOWN

  COMMAND: @chown <object>[=<player>]
           @chown <object>/<attr>[=<player>]

  The first form changes the ownership of <object> to <player> (default is
  to yourself).  Objects may be things, rooms or exits. To chown things, you
  have to be carrying the thing. For rooms or exits, you have to be in the
  room. Objects must have the CHOWN_OK flag set before they may be @chowned.
  In a room, the command used must be @chown here = <name>, and for an object,
  you must be very specific.

  The second form changes the ownership of the indicated attribute on <object>
  to <player> (default is the owner of the object).  You may only @chown
  unlocked attributes.  You may @chown unlocked attributes on objects that
  you own to yourself, and you may also @chown attributes that you own on
  objects owned by others to the owner of the object.

  When an object is @chowned, all unlocked attributes on the object are
  automatically @chowned as well, locked attributes remain owned by their
  original owners.

  The HALTED flag is automatically set on the new copy of the object.
  Players can't be @chowned; they always own themselves.

  Related Topics: @lock, @Unlock, CHOWN_OK, ATTRIBUTE OWNERSHIP.

& @CHZONE
@CHZONE

  COMMAND: @chzone <object>=<zone object>.

  Changes the zone of <object> to <zone object>. If <zone object> is "none",
  the zone is reset to NOTHING.

  @chzone'ing a player does not automatically change the zone of their
  objects. Anyone may reset the zone of an object they own; <zone object>
  must either be "none", or must be owned by them. Only wizards may @chzone
  an object to an arbitrary zone object. Players may @chzone themselves to
  an object they own; otherwise, only wizards may @chzone players.
  @chzone'ing resets the WIZARD, ROYALTY, and INHERIT flags on non-player
  objects.

& @CLIST
@CLIST

  COMMAND: @clist[/<option>]

  Without any switches, it will display the list of public channels with
  their owner and description. It will also display all channels you own.

  <option>, if given, may be either of the following:

    full    - @clist will display more detailed information including
              the channel object's dbref.

    headers - Shows the @clist report with the description column
              replaced by the a column of the channel headers.

  Examples:
    >@clist
    *** Channel Owner Description
    --- Public God No description.
    --- Staff God No description.

    >@clist/full
    *** Channel      --Flags--  Obj   Own   Charge  Balance  Users   Messages

  COMMAND: @clone[/<switches>] <object>[=<newname/cost>]

  Creates an exact duplicate of <object> that is owned by you and (for things
  and exits) puts it in your current location.  You may have the object put
  in your inventory (or your exitlist in the case of cloning exits) by using
  the /inventory switch.

  You may clone your own objects, plus VISUAL objects owned by others.
  The INHERIT and WIZARD bits of the (new) object are cleared when the object
  is cloned.  If <newname> is specified, it is used as the name instead of
  the original name.

  If you clone a linked exit, an attempt is made to link the clone to the
  same location.  Except when using the /inventory switch, you can only clone
  exits when you own your current location.

  If you clone a room with a drop-to, an attempt is made to link the drop-to
  to the same location.

  If the original object was owned by you, then the ACLONE attribute is run
  in the new attribute, otherwise the new object is set HALTED.  Exits and
  contents of cloned objects are not cloned, and LOCKED attributes are not
  copied.

{ 'help @clone2' for more }

& @CLONE2
@CLONE (continued)

  The following switches are available:
     /cost       - Treat the argument after the = as the cost of the new
                   object, not the name.
     /inherit    - Don't reset the INHERIT bit on the new object.
     /inventory  - Create the new object in your inventory (or your exitlist,
                   in the case of cloning exits).
     /location   - Create the new object in your location (default).
     /parent     - Set the new object's parent to be the template object and
                   don't copy the attributes.

& @COFLAGS
@COFLAGS

  COMMAND: @coflags <channel>=[!]flag

  Sets object flags for that channel. The flag can be one of: join, transmit
  or receive.

    transmit   Whether an object can broadcast (speak) over the channel.
    join       Whether an object can join the channel.
    receive    Whether an object can receive messages over the channel.

  NOTE: Flags must be lower case.

  If it is !flag, then that flag is reset. Channel flags ALWAYS override
  locks on channel objects.

  Example:
    > @coflags Public=join
    @coflags: Set.

  Related Topics: @cpflags, @clist, CHANNEL OBJECT.

& @CONFORMAT
@CONFORMAT

  COMMAND: @conformat <object> [=<format>]

  Replaces the usual "Contents:" or "Carrying:" format when an object
  is looked at, by a player-specified contents format. This is evaluated
  as if it were a description or other similar message on the room.
  The objects that the looker would normally be able to see is passed
  as a dbref list in %0; all contents can be acquired through 'lcon(me)'.
  The contents name is passed in %1.

  One could change the format to 'Contents: Object1 Object2 Object3'
  through '@conformat here = %1 [iter(%0,name(##))]',
  for example. More complex things are possible.

  Related Topics: @exitformat, @nameformat

& @COST
@COST

  COMMAND:   @cost <object> = <amount>
  ATTRIBUTE: Cost

  Sets the number of coins that need to be given to an object to trigger the
  Pay, Opay, and Apay attributes.  If the object is given more than this
  amount, the excess is returned to the giver, while if less than this amount
  is given the entire amount is returned, a snide message is sent to the
  giver, and the Apay, Opay, and Pay attributes are not used.

  This attribute is only meaningful for things, and will never be
  automatically triggered on other object types.

  Example: @cost Coke machine = 25

  Related Topics: give, @apay, @opay, @pay.

& @CPATTR
@CPATTR

  @cpattr <obj>/<attr> = <obj1>/<attr1> [,<obj2>/<attr2>,<obj3>/<attr3>,...]
  @cpattr <obj>/<attr> = <obj1> [,<obj2>,<obj3>,...]
  @cpattr <attr> = <obj1>/<attr1> [,<obj2>/<attr2>,<obj3>/<attr3>,...]
  @cpattr <attr> = <obj1> [,<obj2>,<obj3>,...]

  The first form of this command is used to copy <attr> on <obj> to the
  object-attribute pairs in a comma-separated list. For example:

  @cpattr test/va = test/vb, cube/va, tribble/foo

  would copy the VA attribute from object "test" to VB on "test",
  VA on "cube", and FOO on "tribble".  <objN> is matched as if
  you were performing a @set on it.

  The second form copies <attr> to the list of objects, with the name
  <attr>. The third form copies <attr> from the object that executes the
  @cpattr, to the object-attribute pairs in the list. Finally, the fourth
  form copies <attr> from the object that executes the @cpattr to the
  objects in the list, with the name <attr>.

& @CPFLAGS
@CPFLAGS

  COMMAND: @cpflags <channel>=[!]flag

  Sets player flags for that channel. The flag can be one of: join, transmit
  or receive.

    transmit   Whether a player can broadcast (speak) over the channel.
    join       Whether a player can join the channel.
    receive    Whether a player can receive messages over the channel.

  NOTE: Flags must be lower case.

  If it is !flag, then that flag is reset. Channel flags ALWAYS override
  locks on channel objects.

  Example:
    > @cpflags Public=join
    @coflags: Set.

  Related Topics: @coflags, @clist, CHANNEL OBJECT.

& @CREATE
@CREATE

  COMMAND: @create <name> [=<cost>]

  Creates a thing with the specified name.  Creation costs either <cost>
  or 10 coins, whichever is greater. The value of a thing is proportional
  to its cost, specifically, value=(cost/5)-1.  The value may not be greater
  than 100, values that would be greater than 100 are rounded down to 100.

  Related Topics: @destroy, OBJECT TYPES

& @CSET
@CSET

  COMMAND: @cset/<option> <channel>[=<value>]

  Changes the way a channel behaves. <option> can be one of the
  following:

    public  - channel is listed in everyone's @clist.
    private - channel is hidden from the @clist.
    loud    - channel announces player connects/disconnects.
    mute    - shuts connects/disconnects off.
    quiet   - same as mute.
    spoof   - allows the comtitle to replace the player's name.
    anon    - same as spoof.
    nospoof - channel will append the player's name to the comtitle.
    header  - Changes the prefix text used to announce a channel emit to
              <value>. <value> may contain color.
    object  - Sets the channel object to <value>. You must create an object
              before associating a channel with it.
    log     - Sets the maximum number of channel messages to log. 
              The channel must have an object.

  You can set a description for the channel by changing the description
  of the channel object. Also, the channel object's lock will be used
  to check to see if people should be able to join the channel or not.

  Examples:
    > @cset/public Public
    @cset: Channel Public placed on the public listings.
    > @cset/object Public=#5
    Channel Public is now using Garou Channel Object(#5) as channel object.

  Related Topics: CHANNEL OBJECT, @ccreate, @create

& @CWHO
@CWHO

  COMMAND: @cwho <channel>[/all]

  For channels that you own, identifies all connected players on the channel
  and their stats for the channel. If switch is /all, then it also displays
  unconnected players.

  Example:
    > @cwho Public/all
    Name Status Player
    Beowulf on yes
    Ronan on yes

  Related Topics: @clist.

& @DAILY
@DAILY

  COMMAND:   @daily <object>=<command-list>
  ATTRIBUTE: Daily

  This attribute is automatically triggered once per day. No guarantees are
  made as to what time it will execute.

& @DECOMPILE
@DECOMPILE

  COMMAND: @decompile[/dbref] <thing>[/attr] [=<newname>]

  Dumps the sequence of commands you would have to type to clone <thing>.
  This is handy for saving your objects in a text file in case the MUX dies
  a horrible death, or for moving your pride-and-joy creation from one MUX
  to another.  @decompile works on all object types.
  If you specify <newname>, then the commands emitted will set attributes,
  locks, and flags on an object named <newname> and will omit the command
  to create the object.
  If you specify <thing>/<attr>, <attr> accepts wildcards.
  If you specify the /dbref switch, you will get output using the dbref
  number instead of the object name.

  Related Topics: examine, look.

& @DESCRIBE
@DESCRIBE

  COMMAND:   @describe <object> = <description>
  ATTRIBUTE: Desc

  Sets the description for <object>, which others see when they look at the
  object.  Giving all your objects, rooms, and exits good descriptions is
  considered to be good building practice.

  Function references and %-substitutions are allowed in descriptions, and
  are evaluated when someone looks at the object.  In function references,
  'me' refers to the object being looked at, while %-substitutions that refer
  to the enactor (such as %n, %#, %p, etc) refer to the looker.

  Examples:
    <object> @desc vase = You see a delicate Ming vase.
    <exit>   @desc elevator = There is an elevator to the east.

  Related Topics: look, @adescribe, @odescribe.

& @DESCFORMAT
@DESCFORMAT

  COMMAND: @descformat <object> [=<format>]

  Normally, the description of an object is controlled by the content and
  formatting found in the DESCRIBE attribute.  With the WOD_REALMS package
  enabled, DESCRIBE can be substituted in favor of other attributes.

  However, in all cases, @descformat provides one final pass over the
  appearance of an object.  The evaluated description text is passed as %0,
  and the attribute name where this text can be found is passed as %1.  The
  unevaluated description can be acquired using v(%1).

  This is useful to achieve a consistent 'look' using room parents.

  Related Topics: @conformat, @exitformat, @nameformat.

& @DESTROY
@DESTROY

  COMMAND: @destroy[/<switches>] <object>

  This command destroys <object> and refunds its cost of creation to its
  owner.  You must own <object> in order to @destroy it, unless its
  DESTROY_OK flag is set, in which case anyone holding it may @destroy it.
  Rooms, exits, and objects may be destroyed, although the actual
  destruction of rooms is delayed for up to ten minutes and the GOING flag
  is set on the victim room.  Clearing the GOING flag on the room spares it
  from destruction.

  If a thing OR its owner is set DESTROY_OK, the thing will be destroyed
  with no delay. This can also be performed with the /instant switch.

  The @destroy command will not destroy objects with the SAFE flag set unless
  the /override switch is specified.  The DESTROY_OK flag overrides the
  protection given by the SAFE flag.

  The following switches are available:
    /override  - Negate protection offered by the SAFE flag.
    /instant   - Destroy with no delay.

  Related Topics: DESTROY_OK, SAFE.

& @DFAIL
@DFAIL

  COMMAND:   @dfail <object> = <message>
  ATTRIBUTE: Dfail

  Sets the message that a player sees when he tries to drop the object but
  fails because he didn't pass the object's drop lock.

  Function references and %-substitutions are allowed in drop failure
  messages, and are evaluated when someone drops the object.  In function
  references, 'me' refers to the object being dropped, while %-substitutions
  that refer to the enactor (such as %n, %#, %p, etc) refer to the dropper.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Example: @dfail sword = The sword has welded itself to your hand.

  Related Topics: drop, @adfail, @odfail, @lock.

& @DIG
@DIG

  COMMAND: @dig[/<switches>] <name> [= <exitlist> [, <exitlist>] ]

  Creates a new room with the specified name and displays its number. This
  command costs 10 coins. If the [= <exitlist>] option is used, an exit will
  be opened from the current room to the new room automatically.  If the
  second <exitlist> option (after the comma) is specified, an exit from the
  new room back to the current room with the specified [Exits] name is
  opened.  Either exit creation may fail if you do not have sufficient
  rights to the current room to open or link the new exit.
  Example: The command

     @dig Kitchen = Kitchen;k;north;n,south;s

  will dig a room called Kitchen, and open an exit called 'Kitchen' in your
  current room.  The ; symbol means that you may enter the exit by typing
  'k', 'north' or 'n' also.  This command also opens the exit 'south;s' from
  'Kitchen' back to where you are.  Only the first Exit name is displayed in
  the Obvious exits list.

  If you specify the /teleport switch, then you are @teleported to the
  room after it is created and any exits are opened.

  Related Topics: @destroy, @link, @open, LINKING, OBJECT TYPES.

& @DOING
@DOING

  COMMAND: @doing[/<switches>] [<message>]

  Sets your DOING message, which appears after your name in the WHO
  report.

  The following switches are available:

    /poll             - Displays the current poll message from the WHO report.
    /header <message> - Sets a new poll message in the WHO report.
    /unique           - Only set DOING message for the current connection.
    /quiet            - Suppress 'Set.' notification message.

  Related Topics: WHO, @poll.

& @DOLIST
@DOLIST

  COMMAND: @dolist[/<switch>] [<delimiter>] <list>=<action>

  <list> is a list of strings, which can be object numbers, attributes, or
  arbitrary words.  <action> is a command to perform once for each item in
  <list>, replacing the special symbol ## with the corresponding item from
  <list>, and the symbol #@ with the position in the list, starting with
  one. By default, @dolist considers each item in <list> to be separated
  with spaces. If you specify the /delimit switch, then each item is
  considered to be separated by <delimiter>. <delimiter> must be a single
  character.

  If present, <switch> can be any of:
    /space   - (Default) List elements are separated by spaces.
    /delimit - List elements are separated by <delimiter>.
    /notify  - Queues an '@notify' after all commands in the list.

  This command is particularly handy with lcon() and lexits(). A few examples:

    @dolist [lcon(here)] = "[name(##)](##)
    @dolist [lcon(here)] = @switch [get(##/last)]=*1990*,"[name(##)]
    @va me = va vb vc
    @dolist [get(me/va)] = @emit [get(me/##)]
    @dolist Frodo Bilbo Gandalf = page ## = HELP!!!!  I've fallen into a pit.
    @dolist/delimit , {Frodo, Bilbo Baggins, Gandalf} = page ## = HELP!!!!
    @wait me="This is a semaphore.
    @dolist/notify lnum(3)=say ##
    > You say, "This is a semaphore."
    > You say, "0"
    > You say, "1"
    > You say, "2"

  Related Topics: iter(), parse(), @notify, SEMAPHORES.

& @DRAIN
@DRAIN

  COMMAND: @drain <object>

  Discards all commands waiting on the semaphore <object> and resets the
  semaphore to its initial state.

  Related Topics: @notify, @ps, SEMAPHORES

& @DROP
@DROP

  COMMAND:   @drop <object> = <message>
  ATTRIBUTE: Drop

  Sets the message that a player sees when he drops the object, or after he
  goes through the exit.

  Function references and %-substitutions are allowed in drop messages, and
  are evaluated when someone drops the object.  In function references,
  'me' refers to the object being dropped, while %-substitutions that refer
  to the enactor (such as %n, %#, %p, etc) refer to the dropper.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Examples: <object> @drop vase = You gently put down the delicate vase.
            <exit>   @drop elevator = The elevator doors close behind you.

  Related Topics: drop, @adrop, @odrop, DROP-TO, EXITS.

& @EALIAS
@EALIAS

  COMMAND:   @ealias <object> = <entrance-list>
  ATTRIBUTE: Ealias

  Sets up a set of alternate commands that may be used as synonyms for the
  command 'enter <object>' when you are in the same location as the object.
  The alternate commands are separated by semicolons just like in exit names.

  Entry aliases are checked for after exitnames, builtin MUX commands, and
  leave aliases for the current location, but before $-commands.  If more than
  one object has an entry alias that matches a player's command, the one on
  the object that occurs first in the location contents list is used.

  This attribute is meaningful for players and things, and will never be
  automatically looked at on rooms or exits.

  Example: @ealias car = get in car; car; climb in; go for a ride

  Related Topics: @lalias, enter, leave.

& @EDIT
@EDIT

  COMMAND: @edit <object>/<wild-attr> = <search>,<replace>
           @edit <object>/<wild-attr> = ^,<text>
           @edit <object>/<wild-attr> = $,<text>

  This command edits the contents of one or more attributes of an object,
  eliminating the need to retype a long attribute in order to make a simple
  change.  In the first form, all occurrences of <search> in the specified
  attribute of the named object are replaced with <replace>.  Use curly
  braces ({ and }) around <search> or <replace> if they contain commas.
  The second and third form prepend and append <text> to the selected
  attributes, respectively.

  If <wild-attr> contains wildcard characters, then all attributes that
  match are edited.

& @EFAIL
@EFAIL

  COMMAND:   @efail <object> = <command-list>
  ATTRIBUTE: Efail

  Sets the message that a player sees when he tries to enter the object but
  fails because the object is not ENTER_OK or the player fails the
  object's enter lock.

  Function references and %-substitutions are allowed in efail messages, and
  are evaluated when someone fails to enter the object.  In function
  references, 'me' refers to the object that the enactor tried to enter, while
  %-substitutions that refer to the enactor (such as %n, %#, %p, etc) refer to
  the player who tried (and failed) to enter.

  The enter lock only affects the 'enter' command and its aliases (set via
  the @ealias command), it does not affect exits that lead to the object or
  teleporting in.

  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.

  Example: @efail car = The car's door is locked.

  Related Topics: @aefail, @aenter, @ealias, @enter, @oefail, @oenter, enter,
      ENTER_OK.

& @EMIT
@EMIT

  COMMAND: @emit[/<switches>] <message>

  Sends <message> to everyone in your current location without prefixing it by
  your character name.  You can also send the message to everyone in the room
  that contains the object you are inside with the /room switch.

  The following switches are available:

     /here  - Sends the message to everyone in the same location as you.
     /html  - Sends the message to HTML-flags players.
     /room  - Sends the message to everyone in the room that contains the
             object you are in.  Starting from your location, this switch
             'leaves' objects until it reaches a room, and @emits the message
             there.

  If both switches are specified, the message is sent to both places.  If
  neither is specified, /here is assumed.

  Some MUXes may restrict the use of this command.

  Related Topics: @femit, @oemit, @pemit, @npemit, @remit, SPOOFING.

& @ENTER
@ENTER

  COMMAND:   @enter <object> = <message>
  ATTRIBUTE: Enter

  Sets the message that a player sees when entering an object or room,
  whether by using an exit, the enter or leave commands, or by teleporting.

  Function references and %-substitutions are allowed in enter messages, and
  are evaluated when someone enters the object.  In function references,
  'me' refers to the object being entered, while %-substitutions that refer
  to the enactor (such as %n, %#, %p, etc) refer to the player entering the
  object.

  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.

  Example: @enter car = You climb into the car and buckle your seatbelt.

  Related Topics: enter, @aenter, @oenter, ENTER_OK.

& @ENTRANCES
@ENTRANCES

  COMMAND: @entrances [[<object>][,<low>[,<high>]]]

  Lists links from elsewhere to the specified object (default: your current
  room).  For rooms, exits and drop-to's, leading to the room and players
  and objects whose home is in the room are listed.  For players and objects,
  lists exits leading to them.  Because this command is computationally
  expensive, it costs 100 coins.  <low> and <high> can be used to indicate
  where to start and stop the search, respectively.

  Examples:
    > @entrances             <- all links to here
    > @entrances object      <- all links to object
    > @entrances ,100,200    <- all links to here from #100 to #200
    > @entrances me,1000     <- all links to me from #1000 and above.

  Related Topics: @link, @unlink.

& @EXITFORMAT
@EXITFORMAT

  COMMAND: @exitformat <object> [=<format>]

  Replaces the usual "Obvious Exits:" format when an object is looked
  at, by a player-specified exits format. This is evaluated as if it
  were a description or similar message on the room.  The objects that
  the looker would normally be able to see is passed as a dbref list
  in %0; all exits can be acquired through 'lexits(me)'.

  One could change the format to 'Exits: Exit1 Exit2 Exit3' through
  '@exitformat here = Exits: [iter(%0,name(##))]', for example.

  Related Topics: @conformat, @nameformat

& @EXITTO
@EXITTO

  COMMAND:   @exitto <object> = <dbref function>
  ATTRIBUTE: Exitto

  This attribute is used to create variable exits.  If an @exitto is present
  on an exit, and the <dbref function> returns a number or a dbref, the exit
  behaves as if the returned dbref is the exit's destination.

  Because this can be used to go anywhere, @exitto is a wizard-only
  attribute.

  Even though @exitto take precendence over the static destination of an exit,
  don't forget to @link all exits anyway.  Anyone can @link an unlinked exit
  and therefore 'own' and @destroy it.

  Example:
    > @open FooExit
    Opened.
    > @exitto FooExit=#123
    Set.
    > FooExit
    Room123(#123)

  Related Topics: EXITS.

& @FAIL
@FAIL

  COMMAND:   @fail <object> = <message>
  ATTRIBUTE: Fail

  Sets the failure message for <object>.  This message is seen by the actor
  when one of these events occurs:

    - For exits: Someone tries to traverse the exit but cannot because they
      fail the exit's default lock or the exit is not linked.
    - For players and things: Someone tries to pick up the object but cannot
      because they fail the object's default lock.
    - For rooms, players, and things: Someone looks around inside the room,
      player, or thing and fails the object's default lock.

  Substitution and evaluation is performed on the message before it is shown.

  Example:
    > @fail table = It's too heavy to lift!                            <thing>
    > @fail doorway = The doorknob does not turn.                       <exit>

  Related Topics: get, @afail, @ofail, FAILURE.

& @FEMIT
@FEMIT

  COMMAND: @femit[/<switches>] <object>=<message>

  Forces <object> to emit <message>.  This command is similar to the command
  '@force <object> = @emit <message>', except that it will work so long as
  you own the object, whereas @force may fail if the object has its INHERIT
  flag set and the object performing the @force does not.

  The following switches are available:
     /here  - Sends the message to everyone in the same location as <object>.
     /room  - Sends the message to everyone in the room that contains the
              object that <object> is in.  Starting from your location, this
              switch 'leaves' objects until it reaches a room, and @emits the
              message there.

  If both switches are specified, the message is sent to both places.  If
  neither is specified, /here is assumed.

  Some MUXes may restrict the use of this command.

& @FILTER
@FILTER

  COMMAND:   @filter <object> = <pattern>[, <pattern>...]
  ATTRIBUTE: Filter

  This attribute specifies a series of patterns to be used to suppress
  text normally forwarded by the AUDIBLE flag.  If the desired pattern
  contains a comma, the pattern may be enclosed in curly braces {}.

  Example:
    > @fo test=out
    > @set #378=puppet
    test> test grows ears and can now hear.
    > @filter out = {* has arrived.},{* has left.}
    Set.
    > :has not arrived.
    Wizard has not arrived.
    test> From a distance, Wizard has not arrived.
    > :has arrived.
    Wizard has arrived.

  Related Topics:  AUDIBLE, @forwardlist, @infilter, @inprefix, @prefix.

& @FIND
@FIND

  COMMAND: @find <name>[,<low>[,<high>]]

  Displays the name and number of every room, thing, or player that you
  control whose name matches <name>. Because the command is computationally
  expensive, it costs 100 coins.

  <low> and <high> may be used to restrict the range of objects that are
  searched, if they are given then the search starts at object #<low> and ends
  at object #<high>.

  Examples:
    > @find Lost Room
    > @find Secret Device,12000,14000

  Related Topics: @search.

& @FORCE
@FORCE

  COMMAND: @force <player/object>=<command>

  Forces the game to act as though <player/object> had entered <command>.
  You may only force objects that you control.  Objects may not force players
  unless either the object or the player has their INHERIT flag set, and
  objects that do not have their INHERIT flag set may not force objects that
  do.  If the victim is specified by number, you may use an alternate form
  of the command, '#<number> <command>'.

  Related Topics: puppets.

& @FORWARDLIST
@FORWARDLIST

  COMMAND:   @forwardlist <object> = <dbref-list>
  ATTRIBUTE: Forwardlist

  Specifies a list of locations (specified by their db numbers) that are to
  receive messages heard by <object> (filtered by the @filter attribute and
  prefixed by the @prefix attribute).  The messages are only forwarded if
  <object> has its AUDIBLE flag set.

  Related Topics: @filter, @prefix, AUDIBLE.

& @FPOSE
@FPOSE

  COMMAND: @fpose[/<switches>] <object>=<message>

  Forces <object> to pose <message>.  This command is similar to the command
  '@force <object> = :<message>', except that it will work so long as you
  own the object, whereas @force may fail if the object has its INHERIT flag
  set and the object performing the @force does not.

  The following switches are available:
     /default - (default) Put a space between the name of the object and
                the message (ie, send '<name> <message>').
     /nospace - Don't put a space between the name of the object and the
                message (ie, send '<name><message>').

& @FSAY
@FSAY

  COMMAND: @fsay <object>=<message>

  Forces <object> to say <message>.  This command is similar to the command
  '@force <object> = say <message>', except that it will work so long as you
  own the object, whereas @force may fail if the object has its INHERIT flag
  set and the object performing the @force does not.

  Related Topics: @femit, @fpose, INHERIT, say.

& @GFAIL
@GFAIL

  COMMAND:   @gfail <object> = <message>
  ATTRIBUTE: Gfail

  Sets the message that a player sees when he tries to give away the object
  but fails because he didn't pass the object's give lock.

  Function references and %-substitutions are allowed in give failure
  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the object being given away, while
  %-substitutions that refer to the enactor (such as %n, %#, %p, etc) refer
  to the (attempted) giver.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Example: @gfail sword = You can't give away a cursed sword!

  Related Topics: give, @agfail, @ogfail, @lock.

& @HALT
@HALT

  COMMAND: @halt [<object>]

  Halts all commands being run by <object>, or by the object running the
  command if no <object> is given.  If the object to be halted is a player,
  then all commands being run by objects owned by that player are halted.
  Use this command to stop runaway objects and infinite loops.
  The process of halting an object involves removing all commands waiting
  to be run by the object from the queue and refunding the queue deposit.
  Halting an object does not affect commands waiting on it as a semaphore.

  Related Topics: @drain, @notify, kill, HALTED, SEMAPHORES.

& @IDESC
@IDESC

  COMMAND:   @idesc <object> = <message>
  ATTRIBUTE: Idesc

  Sets the internal description for <object>.  The internal description of an
  object will be shown to any player entering it.  If not set, the regular
  description in the Desc attribute is shown instead.

  Function references and %-substitutions are allowed in inside descriptions,
  and are evaluated when someone fails to get or look at the object.  In
  function references, 'me' refers to the object being looked at, while
  %-substitutions that refer to the enactor (such as %n, %#, %p, etc)
  refer to the player doing the looking.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Example: @idesc car = You are sitting in the driver's seat of a Volkswagen
                        Beetle.

  Related Topics: enter, @describe, ENTER_OK.

& @IDLE
@IDLE

  COMMAND:   @idle <object> = <message>
  ATTRIBUTE: Idle

  This attribute is sent as a message to anyone who successfully pages you.
  It can be used to tell someone who pages you when you will return
  (if you are going to be away for a while).

  This attribute is only meaningful for players, and will never be
  automatically referenced on other object types.

  If an @idletimeout is set on the person being paged, you will only see
  the @idle message if that person is more idle than the specified amount
  of time.

  Example: @idle me = At dinner.  Back about 7PM.

  Related Topics: @away, @idletimeout, @reject, page.

& @IDLETIMEOUT
@IDLETIMEOUT

  COMMAND:   @idletimeout <object> = <seconds>
  ATTRIBUTE: IdleTimeout

  This attribute is used to determine if your @idle message is sent to
  a player who successfully pages you.
  If you're online and working at the same time, you can set the minimum
  idle time to allow your message to show. so whilst you're not idle your
  @idle message will not show without you having to delete it to hide it.

  This attribute is only meaningful for players, and will never be
  automatically referenced on other object types.

  Example: @idle me = Working IRL. Monitoring this window from time to time.
           @idletimeout me = 60

  Related Topics: @away, @idle, @reject, page.

& @IFELSE
@IF

  COMMAND: @if <string>=<true>[,<false>]

  Checks if <string> evaluates to a true value. If so, the command <true>
  is performed. If not, <false> is (if present).
  This command can also be called as @ifelse.

  Examples:
    > think money(me)
    150
    > @if [gte(money(me),1)]=say I have money., say I'm broke!
    You say, "I have money."

  Related topics: @switch, ifelse(), switch().

& @INFILTER
@INFILTER

  COMMAND:   @infilter <object> = <pattern>[, <pattern>...]
  ATTRIBUTE: Infilter

  This attribute specifies a series of patterns to be used to suppress
  text normally sent to the contents of <object> by @listen.  If the desired
  pattern contains a comma, the pattern may be enclosed in curly braces {}.

  Example:
    > @listen sports car=*
    > @fo test=enter sports car
    test has left.
    test> Sports Car(#383Q)
    > :waves.
    test> Wizard waves.
    Wizard waves.
    > @infilter sports = *waves*
    > :waves.
    Wizard waves.
    > :knocks on the window.
    test> Wizard knocks on the window.
    Wizard knocks on the window.

  Related Topics: @filter, @inprefix, @listen, @prefix.

& @INPREFIX
@INPREFIX

  COMMAND:   @inprefix <object> = <prefix text>
  ATTRIBUTE: Inprefix

  This attribute, when set, will prefix all text that is sent to the contents
  of <object> by @listen.  The default is to have no prefix, the text is
  forwarded unadorned.

  Example:
    > @listen sports car=*
    > @fo test=enter sports car
    test has left.
    test> Sports Car(#383Q)
    > :waves.
    test> Wizard waves.
    Wizard waves.
    > @inprefix sports car = In the mundane world outside,
    test> In the mundane world outside, Wizard waves some more.
    Wizard waves some more.

& @KILL
@KILL

  COMMAND:   @kill <object> = <message>
  ATTRIBUTE: Kill

  This command sets the message that is shown to anyone who kills <object>.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Function references and %-substitutions are allowed in kill messages, and
  are evaluated when someone kills the object.  In function references, 'me'
  refers to the object that was killed, while %-substitutions that refer to
  the enactor (such as %n, %#, %p, etc) refer to the player doing the killing.

  Example: @kill guard = The guard says "I'll get.. you... for... this... %n"
                         as he falls down and dies.

  Related Topics: kill, @akill, @okill, BEING KILLED, IMMORTAL, WIZARD.

& @LALIAS
@LALIAS

  COMMAND:   @lalias <object> = <entrance-list>
  ATTRIBUTE: Lalias

  Sets up a set of alternate commands that may be used as synonyms for the
  command 'leave' when you are inside a player or a thing.  The alternate
  commands are separated by semicolons just like in exit names.

  Leave aliases are checked for after exitnames and builtin MUX commands, but
  before enter aliases and $-commands.

  This attribute is meaningful for players and things, and will never be
  automatically looked at on rooms or exits.

  Example: @lalias car = get out;climb out;out;open door;outside

  Related Topics: @ealias, enter, leave.

& @LAST
@LAST

  COMMAND: @last <player>

  This command displays a short 'connection history' for <player>, showing
  recent successful and failed connection attempts, as well as the total
  number of successful and failed connections.
  You can only display information about yourself.

& @LEAVE
@LEAVE

  COMMAND:   @leave <object> = <message>
  ATTRIBUTE: Leave

  Sets the message that a player sees when leaving an object or room, whether
  by using an exit, the enter or leave commands, or by teleporting.

  Function references and %-substitutions are allowed in leave messages, and
  are evaluated when someone leaves the object.  In function references,
  'me' refers to the object being left, while %-substitutions that refer
  to the enactor (such as %n, %#, %p, etc) refer to the player leaving the
  object.

  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.

  Example: @leave car = You unbuckle your seatbelt and climb out of the car.

  Related Topics: leave, @aleave, @oleave.

& @LFAIL
@LFAIL

  COMMAND:   @lfail <object> = <command-list>
  ATTRIBUTE: Lfail

  Sets the message that a player sees when he tries to leave it but fails
  because the player fails the object's leave lock.

  The leave lock only affects the 'leave' command and its aliases (set via
  the @ealias command), it does not affect going home, using an exit in the
  location, or teleporting out.

  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.

  Example: @lfail plane = You don't have a parachute!

  Related Topics: @aleave, @alfail, @lalias, @leave, @oleave, @olfail, leave.

& @LINK
@LINK

  COMMAND: @link <object>=#<number>/here/home

  When used on a player or a thing, this command sets the object's home
  to the indicated location.  The destination must be owned by you or be an
  ABODE room, and you must pass the destination's LinkLock.

  When used on a room, this command sets the room's drop-to, where objects
  dropped in the room go.  The destination must be a room that is either owned
  by you or is LINK_OK, and you must pass the destination's LinkLock.

  For exits, this command sets the destination if the exit is currently
  unlinked, you control the destination or it is set LINK_OK, and you pass the
  destination's LinkLock.  You can @link an unlinked exit regardless of who
  owns it or the lock set on it, you are made the owner if you successfully
  link to the destination.  Linking an exit costs 1 coin, and if the exit was
  owned by someone else, you also reimburse the former owner 1 coin
  (making the total cost to you 2 coins).

{ 'help @link2' for more }

& @LINK2
@LINK (continued)

  Note that in all the above cases that it is the player performing the @link
  command that must pass the LinkLock, not the object being linked.
  Therefore, you should use the '$' lock qualifier if you want to prevent
  specific players from linking to your LINK_OK locations, as simply locking
  against '*<playername>' does not lock out their puppets.

  Related Topics: @dig, @open, @unlink, DROP-TOS, HOMES, LINKING, OBJECT TYPES.

& @LIST
@LIST

  COMMAND: @list [<option>]

  Lists information from internal databases.  Information is available
  about the following options:
    attributes      - Valid object attributes.
    commands        - Commands that you may use (excluding the
                      attribute-setting commands as well as any exits, and
                      $-commands available).
    costs           - Lists the costs associated with many commands and
                      actions.
    default_flags   - Lists the flags that new objects receive by default
                      when created.
    flags           - Lists the name and letter of all the flags.
    functions       - Lists all the available functions.
    options         - Lists several global options and limits.
    powers          - Lists all powers.
    switches        - Lists what commands support switches and the switches
                      that they do support.
  The information provided by the @list command is definitive, as it reads
  the internal tables to produce the information it displays.  Specifying
  @list with no argument lists the options you may use.

& @LISTEN
@LISTEN

  COMMAND:   @listen <object> = <string>
  ATTRIBUTE: Listen

  This attribute contains a wildcard pattern that the object listens for.
  Anything spoken, posed, emitted, or whispered in the room that <object> is
  in, as well as messages resulting from using objects (such as Opay and Succ
  messages) are checked against the Listen attribute.  When the object hears
  something that matches the pattern, it triggers the Ahear attribute, as
  well as either the Amhear or Aahear attributes, as appropriate,
  substituting %0 the string that matched the first wildcard character in the
  Listen, %1 for the second. etc.  If the pattern in the Listen attribute is
  matched, objects in <object>'s inventory will also hear the message and
  have a chance to match it.  Objects whose Listen attribute is set to
  anything will be listed when a @sweep command is run by someone in the
  same room.

  If the @listen pattern is matched, then the object's contents will
  hear the message also, prefixed by the text in @inprefix if it is set.  Any
  text that matches any pattern specified in @infilter will not be sent to
  the contents.

  Example: @listen camera = * has arrived.
           @ahear camera = @va me = %va %0

  Related Topics: @aahear, @ahear, @amhear, @sweep, @inprefix, @infilter.

& @LISTMOTD
@LISTMOTD

  COMMAND: @listmotd

  Displays the current message-of-the-day.  Note that it is displayed when
  you connect to your character. This will also display the "motd.txt" file.

& @LOCK
@LOCK

  COMMAND: @lock[/<whichlock>] <object>=<key>
           @lock <object>/<attrib>

  The first form locks <object> to a specific key(s).  Type 'help @lock keys'
  for a list of the keys you may use.

  <whichlock> indicates which lock you want to set on the object.  If you
  don't specify one, you set the Default lock. Type 'help @lock locks' for
  a list of the locks you may set and what they are used for.

  The second form locks the indicated attribute of the named object, so that
  when the object is @chowned, the attribute will remain owned by you.
  It may also be used when you own an attribute on an object that you do not
  own, in this case it prevents the object's owner from @chowning the
  attribute to himself, and prevents anyone from modifying or removing the
  attribute.

& @LOCK ATTRIBUTE
@LOCK ATTRIBUTE

  ATTRIBUTE LOCKS:

  Key: <attribute>:<pattern>
       +<attribute>:<wildcard-pattern>
       =<attribute>:<wildcard-pattern>

  You may lock on whether a specific attribute on the player attempting to
  pass the lock matches a pattern.  Example: '@lock thing=sex:m*' will lock
  thing to anyone whose sex starts with an M. Wild cards, greater than and
  less than may be used, for example: '@lock a-f=name:<g' will lock the exit
  a-f against any one whose name is higher than f.

  Both the player testing the lock and every object in his inventory is
  checked, the player passes the lock if any of those objects passes the lock.
  If the attribute name is prefixed by a = then only the player is checked.
  Similarly, if the attribute name is prefixed by a + then only objects in
  the player's inventory are tested.

{ 'help @lock attribute2' for more }

& @LOCK ATTRIBUTE2
@LOCK ATTRIBUTE (continued)

  Note: you may lock against any attribute, but the locked object must be
  able to read the attribute from the player attempting to pass the lock or
  the lock will fail.

  Examples:
    > @lock men's room=sex:m*
    > @lock a-f=name:<g
    > @lock post office=email:*@*

  Related Topics: ATTRIBUTE OWNERSHIP, @lock evaluation.

& @LOCK CARRY
@LOCK CARRY

  CARRY LOCKS:

  Key: +<object>

  You pass a carry lock if you are carrying the named object.

  Example:
    > @lock secret passage = +magic bus
    You can only traverse the secret passage if you are carrying the
    magic bus.  The bus cannot enter the passage on its own (perhaps
    when you are driving it).

  Related Topics: @lock is, @lock normal.

& @LOCK COMPOUND
@LOCK COMPOUND

  COMPOUND LOCKS:

  Key: <key> & <key>
       <key> | <key>
       !<key>
       ( <key> )

  You can make complex locks by combining keys with the logical AND and OR
  operators (& and ! respectively), or by using the NOT operator.  You
  may also group complex locks with parentheses.

  Examples:
    > @lock exit = me & !me
    An impossible lock, nothing can be both you and not you.

    > @lock message = me | *recipient
    Both you and the player recipient may get the message.

& @LOCK EVALUATION
@LOCK EVALUATION

  EVALUATION LOCKS:

  Key: <attribute>/<value>

  Evaluation locks let you evaluate one of your attributes and compare the
  result against a value stored in the lock.  The result must be an exact
  match (no wildcarding allowed, but uppercase and lowercase are considered
  to be the same).  When evaluating the attribute the enactor substitutions
  (%#/%n/etc) are replaced with information about the player trying to pass
  the lock, and 'me' and %! refer to the locked object or exit.

  If you call an indirect lock and the indirect lock is an evaluation lock
  (or is a compound lock that includes an evaluation lock), then the original
  lock object is checked for the attribute first, followed by the object that
  has the actual evaluation lock.  If there are multiple levels of indirection
  the intermediate locks are not checked.

{ 'help @lock evaluation2' for more }

& @LOCK EVALUATION2
@LOCK EVALUATION (continued)

  Examples:
    > @lock bank=checkmoney/1
    > &checkmoney bank=[gt(money(%#),5000)]
    Only people and objects with more than 5000 pennies may pass.
    Note: this lock requires wizard privileges to read the worth of other
    players.

    > @lock divisible_by_five_club = checkdiv/0
    > &checkdiv divisible_by_five_club = [mod(mid(%#,2,20),5)]
    Only objects whose db-number is divisible by 5 may pass.

  Related Topics: @lock attributes.

& @LOCK INDIRECT
@LOCK INDIRECT

  INDIRECT LOCKS:

  Key: @<object>

  You may reference the lock on another object and use the result of
  evaluating that other object's lock.    You pass an indirect lock if you
  pass the default lock on <object>.  This is especially useful if you
  have a large number of objects or exits that want to have the same lock,
  and you want to be able to update one object and have all the other
  locks change at the same time.

  <object> is searched for when you enter the @lock command and its
  database number is stored in the lock, so something like
  '@Lock north=@master.lock' is safe even if you are going to move master.lock
  to another location.

  Examples:
    > @lock master.lock = me
    > @lock north = @master.lock
    > @lock south = @master.lock
    North and south all reference the lock on master.lock, so you may change
    the lock on all three exits by changing master.lock.

  Related Topics: @lock normal.

& @LOCK IS
@LOCK IS

  IS LOCKS:

  Key: =<object>

  You pass an is lock only if you are the named object.

  Example:
    > @lock mystical highway = =magic bus
    Only the magic bus may travel down the mystical highway.  You cannot
    travel the highway if you are carrying the bus.

                                   in MUX programming where a user-defined
                                   lock is needed.

 Note: If a player fails the UseLock on a parent of an object being searched
 for $-commands, then the search for attributes stops and the parent chain is
 not searched further for matches.

& @LOCK NORMAL
@LOCK NORMAL

  NORMAL LOCKS:

  Key: <object>

  You pass a normal lock if you either are the named object or if you carry
  the named object.  <object> may be the name or #number of a thing,  a
  playername prefixed by an asterisk (*<playername>), 'me', or 'here'.

  Examples:

  OWNERSHIP LOCKS:

  Key: $<object>

  You pass an ownership lock if you have the same owner as <object>.

  Examples:
    > @lock mystuff=$me
    Only objects you own may use the mystuff exit.

    > @lock/page me = !$*TinyJerk
    Neither TinyJerk nor any of his objects may page you.

& @MAIL
@MAIL

  @mail[/<switches>] <player-list> = <subject>
  @mail[/<switches>] [<msg-list> [= <target>]]

  @mail invokes the built-in MUX mailer, which allows players to send
  and receive mail. Pronoun/function substitution is performed on
  any messages you may try to send.

  A <player-list> is a space-separated list of recipients, which may be:
        Player names (names with spaces in them should be put in double
                      quotes, ex: "Foo Bar")
        Player dbref #'s
        Message numbers to be replied to.
        A mix of the above, and mail aliases (see @malias)

  A <msg-list> is one of the following:
        A single msg # (ex: 3)
        A message range (ex: 2-5, -7, 3-)
        A sender (ex: *Hunger)
        An age of mail in days (ex: ~3 (exactly 3), <2, >1)
           "days" here means 24-hour periods from the current time.
        One of the following: "read", "unread", "cleared", "tagged", "urgent"
        For certain commands, "all".

& @MAILSUCC
@MAILSUCC

  COMMAND:   @mailsucc <player> = <message>
  ATTRIBUTE: Mailsucc

  Sets a message to be displayed to the sender whenever <player> receives
  mail.

  Example:
    @mailsucc me=Thanks for the mail.

  Related Topics: @amail, @signature, @mail.

& @MALIAS
@MALIAS

  COMMAND: @malias

  This allows you to generate and maintain mailing lists with the mail
  system. All mail aliases start with '*', and are case-sensitive. (*dir is
  different than *Dir).  There are two kinds of mail aliases, Personal
  and Global. Global mailing lists are owned and maintained by the god (#1)
  char and are available for anyone to use.  Generally there will be
  *Wizards, *Admin, *Roleplay, and things of that nature.  Personal mailing
  aliases are mailing lists that you have defined with the @malias command.
  Currently there is no limit to the number of people you can have on a
  mailing alias.

  To begin sending mail to a mailing list, use @mail *<alias>=subject.

  Usage:

  @malias                   Displays a list of all mail aliases.
  @malias *<alias>          Displays a list of people on that alias.
  @malias *<alias>=<list>   Creates that mailing list, using <list>.

{ 'help @malias2' for more }

& @MALIAS2
@MALIAS (continued)

  You can add, remove, rename, chown, redescribe, and delete mailing lists
  with a switch.

  @malias/remove *<alias>=<player>     Removes <player> from *<alias>.
  @malias/desc *<alias>=<description>  Changes the description for *<alias>.
  @malias/add *<alias>=<player>        Adds <player> to *<alias>.
  @malias/rename *<alias>=<name>       Renames that alias. Names must always
                                       begin with '*'.
  @malias/delete *<alias>              Deletes <alias>.
  @malias/chown *<alias>=<player>      Changes the owner of <alias> to
                                       <player>.

  Wizards can use all of the malias commands on any mail alias. Instead of
  trying to figure out different mailing lists with the same name, wizards
  may use #<MALIAS NUMBER> instead of *alias in regards to the command.
  Remember that the alias commands will only recognize aliases owned by #1,
  owned by you, or by number.

  @malias/list                         When invoked by a wizard, it will
                                       list all mailing aliases currently
                                       defined by their number.

& @MONIKER
@MONIKER

  Command: @moniker <object> = <string>
  Attribute: Moniker

  The @moniker command allows you to set accented, multi-color names for
  an item.  This affects contents, inventories, the normal 'look', and
  many other cases.

  The name in @moniker MUST match the name returned by name() minus ANSI
  codes and accent marks or the moniker is ignored in favor of name().

  Examples:
    > @name object=99 Red Balloons
    Name set.
    > @moniker object=99 [ansi(hr,Red)] Baboons
    String entered must match name of target, '99 Red Balloons'.
    > @moniker object=99 [ansi(hr,Red)] Balloons
    Ansi string entered for 99 Red Balloons of '99 Red Balloons'.

& @MOVE
@MOVE

  COMMAND:   @move <object> = <command-list>
  ATTRIBUTE: Move

  Sets the message that an object sees after it moves from one location to
  another, whether by using an exit, entering or leaving an object,
  teleporting, or going home.

  This attribute is meaningful for players, and things and will never be
  automatically triggered on other object types.

  Example: @move bopper = OK.  You're there now.

  Related Topics: @amove, @omove.

& @MVATTR
@MVATTR

  COMMAND: @mvattr <object>=<old>,<new>[,<copy1>]...

  This command moves attributes around on an object.  The attribute <old> is
  renamed <new> (and is copied to <copy1>, <copy2> and so on if specified).
  If you cannot modify the <old> attribute (for instance if you are trying to
  move the Last attribute, or if it were owned by another player), then a new
  copy is made and the original is not removed.

  Related Topics: @set.

& @NAME
@NAME

  COMMAND: @name <object> = <new name>

  Changes the name of <object>.  <object> can be a thing, player, exit, or
  room, specified as <name> or #<dbref> or 'me' or 'here'.

  See '@list options' as to whether or not a player name may contain
  spaces.

& @NAMEFORMAT
@NAMEFORMAT

  COMMAND: @nameformat <object> [=<format>]

  By default, when an object is looked at, the object's name is shown.
  And, if you can link to the object, it's flag letters and dbref are also
  shown. However, with @nameformat, you can control exactly what is shown.

  Related Topics: @conformat, @exitformat

& @NEMIT
@NEMIT

  COMMAND: @nemit[/<switches>] <message>

  Sends <message> to everyone in your current location without prefixing it by
  your character name and without evaluating it.  You can also send the
  message to everyone in the room that contains the object you are inside with
  the /room switch.

  The following switches are available:

     /here  - Sends the message to everyone in the same location as you.
     /html  - Sends the message to HTML-flags players.
     /room  - Sends the message to everyone in the room that contains the
             object you are in.  Starting from your location, this switch
             'leaves' objects until it reaches a room, and @emits the message
             there.

  If both switches are specified, the message is sent to both places.  If
  neither is specified, /here is assumed.

  Some MUXes may restrict the use of this command.

  Related Topics: @emit, @femit, @oemit, @pemit, @npemit, @remit, SPOOFING.

& @NOTIFY
@NOTIFY

  COMMAND: @notify[/<switches>] <object>[/<attribute>][=<count>]

  Notifies the semaphore <object>, running the first command that waited on
  <object> using the '@wait <object>=<command>' or '
  @wait <object>/<time>=<command>' forms of the @wait command.  If <count> is
  specified, it indicates the number of times the semaphore is notified.
  If there are no commands (or less than <count> commands) pending for
  <object>, then subsequent @waits will not block until the semaphore count
  reaches zero again. @notify may also take an argument of the form
  <object>/<attribute>, which notifies commands that are being blocked on
  an attribute other than the default 'Semaphore'. This allows blocking of
  multiple sets of commands on a single object, using different attributes.

  The following switches are available:
     /first - (default) Notify the first command waiting on the indicated
              semaphore (or the first <count> commands).
     /all   - Notify all commands waiting on the semaphore and reset the
              semaphore count to zero.  <count> is ignored.
     /quiet - Suppress the 'Notified.' message associated with the command.

  Related Topics: @drain, @ps, @wait, SEMAPHORES

& @NPEMIT
@NPEMIT

  COMMAND: @npemit[/switches] <what>=<message>

  Almost exactly like @pemit and it takes the same switches. However,
  it does not evaluate <message> at all. So, @npemit differs from
  @npemit/noeval in that no space compression is done.

  Related Topics: @pemit

& @ODESCRIBE
@ODESCRIBE

  COMMAND:   @odescribe <object> = <message>
  ATTRIBUTE: Odesc

  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone looks at <object>.

  Example: @odesc vase = carefully inspects the vase.

  Related Topics: look, @adescribe, @describe, @idesc.

& @ODFAIL
@ODFAIL

  COMMAND:   @odfail <object> = <message>
  ATTRIBUTE: Odfail

  Sets the message (prefixed by the player's name) that is shown to others in
  the same room when someone tries to drop <object> but fails because they
  didn't pass the object's drop lock.

  Function references and %-substitutions are allowed in drop failure
  messages, and are evaluated when someone drops the object.  In function
  references, 'me' refers to the object being dropped, while %-substitutions
  that refer to the enactor (such as %n, %#, %p, etc) refer to the dropper.

  Example: @odfail sword = tries to put down the sword but it leaps back
                                       into %p hand.

  Related Topics: drop, @adfail, @dfail, @lock.

& @ODROP
@ODROP

  COMMAND:   @odrop <object> = <message>
  ATTRIBUTE: Odrop

  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone drops <object>, or to others in the room that the
  player arrives in after taking an exit.

  Example: <object> @odrop loadstone = puts down the loadstone and then
                                       wipes sweat from %p brow.

& @OEFAIL
@OEFAIL

  COMMAND:   @oefail <object> = <command-list>
  ATTRIBUTE: Oefail

  Sets the message (prefixed by the player's name) that is shown to others in
  the same room as the player when he tries to enter the object but fails
  because the object is not ENTER_OK or the player fails the
  object's enter lock.

  The enter lock only affects the 'enter' command and its aliases (set via
  the @ealias command), it does not affect exits that lead to the object or
  teleporting in.

  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.

  Example: @oefail car = tries to open the car's door, but it is locked.

  Related Topics: @aefail, @aenter, @ealias, @efail, @enter, @oenter, enter,

@OENTER

  COMMAND:   @oenter <object> = <message>
  ATTRIBUTE: Oenter

  Sets the message (prefixed by the player's name) that is shown to others in
  the location being entered when someone enters <object>.  Note that the
  message is shown to those inside the object, not those outside.

  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.

  Example: @oenter wormhole = enters the wormhole from normal space.

  Related Topics: enter, @aenter, @enter, @oxenter.

& @OFAIL
@OFAIL

  COMMAND:   @ofail <object> = <message>
  ATTRIBUTE: Ofail

  Sets the others failure message for <object>.  This message is seen others
  in the same location as the actor when one of these events occurs:

    - For exits: Someone tries to traverse the exit but cannot because they
      fail the exit's default lock or the exit is not linked.
    - For players and things: Someone tries to pick up the object but cannot
      because they fail the object's default lock.
    - For rooms, players, and things: Someone looks around inside the room,
      player, or thing and fails the object's default lock.

  Substitution and evaluation is performed on the message before it is shown.

  Examples:
    > @ofail table = tries to pick up the table, but it is too heavy.  <thing>
    > @ofail doorway = tries the knob on the door, to no avail.         <exit>

  COMMAND:   @ogfail <object> = <message>
  ATTRIBUTE: Ogfail

  Sets the message (prefixed by the player's name) that is shown to others in
  the same room when someone tries to give away <object> but fails because
  they didn't pass the object's give lock.

  Function references and %-substitutions are allowed in give failure
  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the object being given away, while
  %-substitutions that refer to the enactor (such as %n, %#, %p, etc) refer
  to the (attempted) giver.

  Example: @ogfail blob = tries to give away a sticky blob of goo.

  the location being left when someone leaves <object>.  Note that the
  message is shown to those inside the object, not those outside.

  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.

  Example: @oleave wormhole = departs the wormhole to return to normal space.

  Related Topics: leave, @aleave, @leave, @oxleave.

@OLFAIL

  COMMAND:   @olfail <object> = <command-list>
  ATTRIBUTE: Olfail

  Sets the message (prefixed by the player's name) that is shown to others in
  the same room as the player when he tries to leave it but fails because the
  player fails the object's leave lock.

  The leave lock only affects the 'leave' command and its aliases (set via
  the @ealias command), it does not affect going home, using an exit in the
  location, or teleporting out.

  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.

  Example: @olfail plane = thinks about jumping out of the plane without a
                           parachute, but wisely reconsiders.

  moved to that location from somewhere else, whether by using an exit,
  entering or leaving an object, teleporting, or going home.

  This attribute is meaningful for players, and things and will never be
  automatically triggered on other object types.

  Example: @omove car = coasts to a stop.

                                Coke machine.  You hear some rumbling from
                                inside the machine and a can of Coke appears
                                in the tray at the bottom of the machine.

  Related Topics: give, @cost, @apay, @pay.

& @OPEN
@OPEN

  COMMAND: @open[/<switches>] <direction list> [=<number>[,<direction list>]]

  Creates an exit in the specified direction(s). If <number> is specified,
  it is linked to that room. Otherwise, it is created unlinked. You or anyone
  else may use the '@link' command to specify where the unlinked exit leads.
  Opening an exit costs 1 coin. If you specify <number>, linking costs 1 more
  coin.  You can specify a second direction list (after the comma), which is
  automatically opened in the room that the new exit goes TO and which is
  linked back to where you are.  I.e.  @open north;n=#1234,south;s
  would open exit 'north;n' from here to #1234, and an exit 'south;s'
  from #1234 to here, assuming you have rights to open exits and link to
  the rooms in question.

  The following switches are available:
     /location  - Create the exit in your location (default).
     /inventory - Create the exit on yourself.

  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the intended recipient of the object,
  while %-substitutions that refer to the enactor (such as %n, %#, %p, etc)
  refer to the (attempted) giver.

  Example: @orfail merchant = tries to unload some worthless trash on Astinous.

& @OSUCCESS
@OSUCCESS

  COMMAND:   @osuccess <object> = <message>]
  ATTRIBUTE: Osucc

  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone picks up the named player or thing, goes through the
  named exit, or looks at the room and passes the room's lock.

  Setting Osuccess messages on all takeable objects and usable exits is
  considered good building practice.

  Examples: <object> @osucc vase = carefully picks up the vase.
            <exit>   @osucc doorway = opens the door and leaves the room.
                                      The door closes behind %o with a click.

  the same room when someone tries to teleport to somewhere he does not have
  permission.  You do not see this message if they couldn't teleport out of
  their present location.

  Function references and %-substitutions are allowed in teleport failure
  messages, and are evaluated when someone attempts to teleport to the
  specified destination.  In function references, 'me' refers to the teleport
  destination, while %-substitutions that refer to the enactor (such as %n,
  %#, %p, etc) refer to the player attempting the teleport.

  When a player teleports another object (@tel <object>=<destination>), the
  lock is checked against the player, not the object.

  Example: @otfail here = thinks about teleporting to the Magic Room, but
                          decides against it at the last moment.

& @PREFIX
@PREFIX

  COMMAND:   @prefix <object> = <prefix text>
  ATTRIBUTE: Prefix

  This attribute, when set, will be used as a prefix for all text forwarded
  by the 'audible' flag on an object or exit.  The default if this attribute
  is not set is 'From <object name>,' for objects, and 'From a distance,'
  for exits.

  Example:
    > @fo test=out
    > @set #378=puppet
    test> test grows ears and can now hear.
    > :does something silly.
    Wizard does something silly.
    test> From a distance, Wizard does something silly.
    > @prefix out=From some strange place
    Set.
    > :does something even sillier.
    Wizard does something even sillier.
    test> From some strange place Wizard does something even sillier.

& @PROGRAM
@PROGRAM

  COMMAND: @program <player>=<obj/attr>[:<prefix>]

  This command allows for small 'programs' within MUX. To understand this
  command, you must first understand the fact that it completely bypasses any
  commands, built-in or otherwise, and allows you to send user-input directly
  into your code.

  A simple example:

  @va me=$start:@prog %#=me/vb:Please enter a word:
  @vb me=@emit You entered %0!;@prog %#=me/vc:Please enter another word:
  @vc me=@emit This time, you entered %0. You're done!

  > start
  Please enter a word:
  > foobar       (Note that @program literally gives you a '>' prompt.)
  You entered foobar!
  Please enter another word:
  > hoopla
  This time you entered hoopla. You're done!

{ 'help @program2' for more }

& @PROGRAM2
@PROGRAM (continued)

  As you can see, this command basically takes what a user types at the
  prompt, stuffs it into %0 in the code in <obj/attr>, and then triggers
  that attribute. Note that when @program triggers an attribute, the enactor
  of that triggered attribute is <player>, and is inserted into %#.
  r-registers are preserved when @program triggers an attribute.

  An optional message, <prefix>, may be specified and will be output before
  the @program prompt. This is useful for telling the user what information
  they need to supply.

  A player caught in @program may send a command through to the normal
  command processor at the @program prompt by prefixing it with the '|'
  character, for example, '|WHO'.

& @PS
@PS

  COMMAND: @ps[/<switches>] [<object>]

  Lists information about the commands you have on each of the queues.
  Unless the /summary switch is used, this command lists all the commands you
  have on the queues, optionally along with their enactor and arguments.
  Commands scheduled to be executed at a later time (by the @wait command)
  also show the number of seconds until they will be executed and/or the
  semaphore on which they are waiting.  If <object> is specified, only
  commands run by <object> are listed, otherwise all commands run by any of
  your objects is listed.  A summary of the number of commands listed and the
  total number of commands in the queues is also displayed.  This command is
  useful for identifying infinite loops in programs.

  The following switches are available:
     /brief   - (default) Display a brief summary that shows the semaphore
                number, time-to-wait, object running the command, and the
                command to be run.
     /long    - In addition to the information in the /brief report, display
                the name and number of the object that caused the command
                to be run (the enactor) and the arguments to the command.
     /summary - Display just the queue counts.

  Related Topics: @notify, @wait.

& @QUITPROGRAM
@QUITPROGRAM

  COMMAND: @quitprogram <player>

  Terminates the @program for player. If <player> is not specified, then it
  works upon the enactor (a player may quit a program while they are in it
  by piping out @quitprogram, see 'help @program').

  Related Topics: @program.

& @QUOTA
@QUOTA

  COMMAND: @quota

  Lists your total building quota and the amount you have remaining.
  Creating objects, digging rooms, and opening exits all consume quota.

  Related Topics: @create, @dig, @open.

& @REJECT
@REJECT

  COMMAND:   @reject <object> = <message>
  ATTRIBUTE: Reject

  This attribute is sent as a message to anyone who tries to page you but
  you have prevented them from paging you via your page lock (@lock/page).

  This attribute is only meaningful for players, and will never be
  automatically referenced on other object types.

  Example: @reject me = I _told_ you not to page me anymore...

  Related Topics: @away, @idle, page.

& @REMIT
@REMIT

  COMMAND: @remit <room dbref#> = <message>

  Sends <message> to the contents of <room>.

  Related Topics: @femit, @oemit, @pemit, @npemit, @emit, SPOOFING.

& @RFAIL
@RFAIL

  COMMAND:   @rfail <object> = <message>
  ATTRIBUTE: Rfail

  Sets the message that a player sees when he tries to give an object to
  someone else, but the receiver refuses to accept the object because
  the object didn't pass its receive lock.

  Function references and %-substitutions are allowed in receive failure
  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the intended recipient of the object,
  while %-substitutions that refer to the enactor (such as %n, %#, %p, etc)
  refer to the (attempted) giver.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Example: @gfail merchant = The merchant doesn't want your worthless trash.

  Related Topics: give, @agfail, @arfail, @gfail, @ogfail, @orfail, @lock.

& @ROBOT
@ROBOT

  COMMAND: @robot <name>=<password>

  Creates a robot player owned by you.  The robot has its ROBOT flag set, so
  it may use the outputprefix and outputsuffix commands that some publicly
  available robot programs require.  This command costs 1000 coins.
  Note that some sites do not restrict outputprefix and outputsuffix to
  robots.

  Related Topics: outputprefix, outputsuffix, ROBOT, OBJECT TYPES.

& @RUNOUT
@RUNOUT

  COMMAND:   @runout <object> = <command list>
  ATTRIBUTE: Runout

  Sets the actions to be taken by <object> when another of its attributes is
  triggered (either automatically or via the @trigger command) and its
  Charges attribute is zero.  When this occurs, the Runout attribute is run
  INSTEAD OF the attribute that would have run normally.

  Example: @runout magic wand = :fizzles and turns to dust.; @destroy me

  Related Topics: @charges.

& @SAYSTRING
@SAYSTRING

  Command: @saystring <object> = <string>

  Sets the substitute string that is used instead of the default 'says,'
  when you talk in a location or on the comsys. The message is passed
  as %0 and the command (say, @fsay, or channel) as %1.

  Example:
    > @saystring me=barks
    > "Hello.
    Player barks "Hello."
    > @saystring me=case(right(%0,1),!,exclaims\,,?,asks\,,says\,)
    > "Hello!
    Player exclaims, "Hello!"

  Related Topics: say, ", @speechmod.

& @SEARCH
@SEARCH

  COMMAND: @search [<player>] [<class>=<restriction>[,<low>[,<high>]]]

  Displays information about objects that meet the search criteria.
  Because this command is computationally expensive, it costs 100 coins.
  <player> restricts the search to the named player, while <class>
  and <restriction> control the objects listed.  Type 'help search classes'
  for a list of the classes you may use.

  Except when getting lists of players ('@search type=player' or
  '@search flags=P'), you may only search for objects that you own.
  You may limit the range of the search with <low> and <high>, which specify
  the objects to start and stop the search at, respectively.  The default for
  <low> is #0 and the default for <high> is the last object in the database.

  Examples:
    @search flags=PWc              <-- search for connected wizards.
    @search type=room              <-- list all rooms owned by me.
    @search eval=gt(money(##),10)  <-- search for things worth more than 10.
    @search type=room,100,300      <-- Rooms between #100 and #300, inclusive
    @search object=Test,5000       <-- Things starting with Test from object
                                       #5000 to the end of the database.
  Related Topics: @find, search().

& @SET
@SET

  COMMAND: @set[/<switch>] <object>=[!]<flag1> [!][<flag2>
           @set[/<switch>] <object>=<attribute>:<value>
           @set[/<switch>] <object>=<attribute>:_<fromobj>/<fromattr>
           @set[/<switch>] <object>/<attr>=[!]<attrflag>

  The first form sets (or clears) the indicated flag or flags on <object>, 
  the second form sets the <attribute> attribute on <object> to <value>,
  creating a new user-named attribute if there is no attribute named
  <attribute>.  The third form copies an attribute from another object, and
  the fourth form sets (or clears) an attribute flag on the <attr> attribute
  of <object>.

  When setting attributes on an object, you may also use the command
  '@<attribute> <object> = <value>' if the attribute is a predefined
  attribute.  You may also use the command '&<attribute> <object> = <value>'
  to set either predefined attributes or user-named attributes.  Either of
  these is equivalent to the second form of the @set command.

{ 'help @set2' for more }

& @SET2
@SET (continued)

  The following flags may be set using the fourth form of the @set command:
     no_command - Prevent $-commands and ^-patterns defined in the attribute
                  from being performed.
     no_inherit - Prevents children of the object from obtaining the
                  attribute.  From their perspective the attribute does not
                  exist.
     visual     - Anyone may see the attribute when they examine you, and
                  may get the attribute with get().
     hidden     - The attribute is only visible to wizards.
     regexp     - When $-commands are matched, treat the pattern as a
                  regular expression rather than a wildcard glob pattern.
     wizard     - The attribute may only be changed by wizards.

  The @set command takes the following switch:
     quiet      - Inhibit 'Set.' acknowledgement messages.

& @SEX
@SEX

  COMMAND:   @sex <object> = <gender>
  ATTRIBUTE: Sex

  Sets the gender for <object>, which is used to determine which pronouns to
  use when replacing %p, %o, %s, and %a parameters in messages that apply to
  <object>.  Genders that start with M or m are considered male, those
  starting with F, f, W, or w are considered female, those starting with
  P or p are considered plural, and anything else is considered neuter.

  Example: @sex me = female
           @sex me = No thank you (Silly, but possible.  Treated as neuter)

  Related Topics: GENDER.

& @SIGNATURE
@SIGNATURE

  COMMAND:   @signature <player> = <message>
  ATTRIBUTE: Signature

  Sets a message to be appended to every @mail message you send. It is
  appended directly at the end of the message, so if you wish to start the
  signature on a new line you should begin it with a %r.

  Example: @signature me=%rThis is a mail signature. (Note: You might want
  to include the %r at the front of the signature, other wise it will be
  combined with the @mail message.)

  Related Topics: @mailsucc, @amail, @mail.

& @SPEECHMOD
@SPEECHMOD

  Command: @speechmod <object> = <string>
  Attribute: SpeechMod

  Sets a filter to be applied to all of <object>'s speech. <string> is
  evaluated with the original speech as %0 and the command as %1. It is
  then displayed in place of the original speech. You can use this to
  colorize each word of what you say, say things backwards, etc. 

  @speechmod affects: "  \\  ;  :  page  pose  say  whisper  @fpose  
     @fsay  @wall  on-channel speech

  %1 may be one of: channel  channel/pose  page  pose  say  whisper
    @emit (for \\)  @fpose  @fpemit  @fsay  @wall

  Example:
    > @speechmod me=ucstr(%0)
    > "Hello.
    Player says "HELLO."

& @STARTUP
@STARTUP

  COMMAND:   @startup <object> = <command list>
  ATTRIBUTE: Startup

  Sets a list of commands to be performed by <object> when the game is
  started up.  Typical actions include going home, cleaning visitors out of
  a room, resetting a puzzle or complex object to its initial state, or
  starting up an object that wants to run continuously.

  Example: @startup me = @vz me=MUX was last restarted at [time()].
           @startup me = home

& @STATS
@STATS

  COMMAND: @stats[/all] [<player>]

  Display the number of objects in the game.  @stats/all gives a
  breakdown by object types.  If <player> is specified, the breakdown
  for the named player is given.  You may only list individual counts
  for yourself.  If invoked with no arguments or switches this command is
  free, but if you specify either /all or <player>, then this command costs
  100 coins to run, because it is computationally expensive.

  Related Topics: stats().

& @SUCCESS
@SUCCESS

  COMMAND:   @success <object> = <message>
  ATTRIBUTE: Succ

  Sets the message that is shown to the player who successfully picks up the
  named player or thing, goes through the named exit, or looks at the room
  and passes the room's lock.

  Example: <object> @succ vase = You carefully pick up the delicate vase.
           <exit>   @succ doorway = You open the door and walk through the
                                    doorway.

  Related Topics: get, look, @asuccess, @osuccess, SUCCESS.

& @SWEEP
@SWEEP

  COMMAND: @sweep[/<switches>]

  This command tells you all of the objects, players, and exits that are
  listening in the room you are currently in, as well as the objects you are
  carrying.  Most objects only listen for a particular string or phrase, so
  they normally do not pose a problem if you need privacy.  You will have to
  be careful of players, puppets, and audible exits since they will hear
  everything you say and do.  There are several switches that may be used to
  limit the type of listeners that are checked for.  They are:
     /here      - Check the room I am in.
     /inventory - Check my inventory.
     /exits     - Check exits in the room.

     /commands  - Check for objects that have $-commands set on them.
     /connected - Check for connected players and their puppets.
     /listeners - Check for objects with @listen set to something.
     /players   - Check for players and their puppets, whether or not they
                  are connected.

  The default is to search for everything.  If you specify one or more
  switches from either category (either location or listener type then only
  that location or listener type is checked.

  Related Topics: @listen, AUDIBLE, PUPPETS.

& @SWITCH
@SWITCH

  COMMAND: @switch[/<switches>] <string>=<t1>,<c1> [,<tN>,<cN>]... [,<cD>]

  Compares <string> against the targets <t1>, <t2>, etc, until a match is
  found, at which time the corresponding list of commands is performed.

  #$ is substituted with the value of <string>. In this way, the commands in
  <c1>..<cN>..<cD> have a short-hand way of getting at the matched value.

  Wildcards match strings, and the < and > operators allowing matching by
  numeric value.  By default, any list whose target matches the string is
  executed (the targets are not mutually exclusive). If no target matches,
  the default list <cD> is executed.

  The following switches are available:

     /all   - (default) Perform the actionlists associated with all targets
              that match <string>.
     /first - Perform only the actionlist associated with the first target
              that matches <string>.

& @TELEPORT
@TELEPORT

  COMMAND: @teleport [<object>=] <room/thing>
           @teleport [<object>=] <exit>
           @teleport [<object>=] home

  The first form of the @teleport command moves <object> (or you) to the named
  room or thing.  The second form sends <object> (or you) to the destination
  of the named exit, while the third form sends <object> (or you) home.
  If the destination room has a drop-to, the object will go to the drop-to
  instead of the named location.

  For the first form of the @teleport command, the object being teleported
  must pass its location's TeloutLock; and you must control the destination,
  or it must be JUMP_OK and you must pass the destination's TportLock.

  The second and third forms let you remove any object from locations you
  control by sending them through an exit or to their home.

  The following switch is available:
     /quiet - Teleports without setting off success or failure messages.

  Related Topics: JUMP_OK, @lock (tport and telout), @tfail, @otfail, @atfail,
      @tofail, @otofail, @atofail.

& @TFAIL
@TFAIL

  COMMAND:   @tfail <object> = <message>
  ATTRIBUTE: Tfail

  Sets the message that a player sees when he tries to teleport to somewhere
  he does not have permission.  You do not see this message if you couldn't
  teleport out of your present location.

  Function references and %-substitutions are allowed in teleport failure
  messages, and are evaluated when someone attempts to teleport to the
  specified destination.  In function references, 'me' refers to the teleport
  destination, while %-substitutions that refer to the enactor (such as %n,
  %#, %p, etc) refer to the player attempting the teleport.

  When a player teleports another object (@tel <object>=<destination>), the
  lock is checked against the player, not the object.

  Example: @tfail here = A psychic barrier prevents you from teleporting there.

  Related Topics: @teleport, @atfail, @otfail, @lock.

& @TOFAIL
@TOFAIL

  COMMAND:   @tofail <object> = <message>
  ATTRIBUTE: Tofail

  Sets the message that a player sees when he tries to teleport from somewhere
  he does not have permission.

  Function references and %-substitutions are allowed in teleport failure
  messages, and are evaluated when someone attempts to teleport out of their
  location.  In function references, 'me' refers to the player's current
  location, while %-substitutions that refer to the enactor (such as %n,
  %#, %p, etc) refer to the player attempting the teleport.

  Example: @tofail here = A psychic barrier prevents you from teleporting
           out.

  Related Topics: @teleport, @atofail, @otofail, @lock.

& @TPORT
@TPORT

  COMMAND:   @tport <object> = <message>
  ATTRIBUTE: Tport

  Sets the message that an object sees whenever it teleports.
  The message is displayed after the object moves to its new location.

  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.

  Example: @tport me = Hey! I teleported. Wow!

  Related Topics: @atport, @otport, @oxtport, @teleport.

& @TRIGGER
@TRIGGER

  COMMAND: @trigger[/<switch>] <object>/<attr> [=<param> [, <param>]... ]

  Invokes an action list stored in an attribute on an object.  The triggering
  object becomes the enactor and the positional parameters %0 through %9
  are set to the supplied parameters.

  The @trigger command supports the following switch:
     quiet      - Inhibit 'Triggered.' acknowledgement messages.

  Related Topics: LOOPING.

& @UFAIL
@UFAIL

  COMMAND:   @ufail <object> = <message>
  ATTRIBUTE: Ufail

  Sets the message that someone sees when they try to use object but fail
  the object's use lock.  Note that the other functions controlled by the use
  lock (paying, listening, and $-commands) do not trigger ufail.

  Example: @ufail robot = The robot pointedly ignores you.

  Related Topics: @aufail, @oufail, @use.

& @UNLINK
@UNLINK

  COMMAND: @unlink <room/exit>

  This command removes drop-tos on rooms and clears the destination on exits.
  Once unlinked, an exit may be taken over by anyone with the @link command.

  Related Topics: @link, LINKING, OBJECT TYPES.

& @UNLOCK
@UNLOCK

  COMMAND: @unlock <object>
           @unlock <object>/<attrib>

  The first form removes the lock on <object>, so that anyone may pass
  through (if an exit) or pick it up (if a player or an object).

  The second form clears the locked flag on the indicated attribute of the
  named object.  This allows the attribute to change ownership to the new
  owner automatically when the object is @chowned, and allows the owner
  of the object to @chown the attribute to themself or to overwrite it.
  You must own the attribute to be unlocked, but you do not need to own the
  object.

  Related Topics: @chown, @lock, ATTRIBUTE OWNERSHIP.

& @USE
@USE

  COMMAND:   @use <object> = <message>
  ATTRIBUTE: Use

  Sets the message that is shown to the player who uses <object>.

  This attribute is only meaningful for players and things, and will never
  be automatically triggered on other object types.

  Example: @use camera = You take a picture with the camera.  Click.

  Related Topics: use, @ause, @ouse.

& @VERB
@VERB

  COMMAND: @verb <victim>=<actor>,<what>,<def>,<owhat>,<odef>,<awhat>,<args>

  This command provides a way to do user-defined verbs with associated
  @attr/@oattr/@aattr groups. Invoking it does the following:

  <actor> sees the contents of <victim>'s <what> attribute, or
    the <def> string if you can't read <victim>'s <what> attribute.
  Everyone in the same room as <actor> sees the contents of
    <victim>'s <owhat> attribute, with <actor>'s name prepended,
    or <odef>, also with <actor>'s name prepended, if you can't read
    <victim>'s <owhat> attribute.
  If you control <victim>, then he executes the contents of his <awhat>
    attribute.

  By supplying up to nine <args>, you may pass those values on
  the stack (i.e. %0, %1, %2, etc. up through %9).

  You must control the actor, but need not control the victim.  Note that
  if you don't have the ability to read the appropriate attributes (whether
  because you control the victim, he is VISUAL, or the attributes are set
  VISUAL), the default messages will be used.

{ 'help @verb2' for more }

& @VERB2
@VERB (continued)

  Here is a description of the arguments to @verb:
    victim - The object that is searched for attributes, and which runs the
             <awhat> attribute if it is found.
    actor  - The object that 'did' the verb, this is the value for %#/%n/etc
             in substitutions, and this object's name is included in the
             message to others in the same location.
    what   - The name of the attribute containing the message to be delivered
             to the actor.
    whatd  - The message to deliver to the actor if the victim does not have a
             <what> attribute, or if it cannot be read.
    owhat  - The name of the attribute containing the message (prefixed by the
             actor's name) that is sent to everyone in the room with the actor.
    owhatd - The message (prefixed by the actor's name) to deliver to others
             in the room with the actor if the victim does not have an <owhat>
             attribute, or it cannot be read.
    awhat  - The name of the attribute that is to be executed by the victim.
    args   - The comma-separated arguments to be passed for substitution
             (%0-%9).  If there is more than one argument, enclose all the
             arguments within curly braces.  Any argument that contains an
             embedded comma needs to be enclosed in curly braces as well.

& @WAIT
@WAIT

  COMMAND: @wait[/until] <seconds>=<command>
           @wait[/until] <object>[/<seconds>]=<command>
           @wait <object>/<attribute>=<command>

  Generally, @wait defers the execution of <command> until some future
  condition or combination of conditions.

  The first form of @wait executes <command> at some future time.

  The second form executes <command> when the object's semaphore is
  notified. If <seconds> is specified in this second form, <command> is
  executed at some future time even if the object's semaphore isn't
  notified. This is sometimes referred to as a 'timeout'.

  The third form allows the use of an attribute other than 'semaphore'. It
  allows multiple sets of semaphore-blocked commands to use the same object.

  This command charges a deposit of 10 coins which is refunded when
  <command> is executed or otherwise leaves the queue.

  By default, <seconds> is relative to the time @wait is processed, however
  if /until used, <seconds> is taken as absolute (See secs, convtime and
  convsecs). <seconds> can also express fractional seconds.

  Examples:
     > @wait 2.001=think FooBar
     FooBar

  COMMAND: @wipe <object>[/<wild-attr>]

  This command erases attributes from an object.  All attributes that match
  <wild-attr> (or all attributes, if <wild-attr> is not specified) are removed
  from <object>.  Attributes that you do not have permission to modify (such
  as read-only or locked attributes) are not removed.

ABS()

  FUNCTION: abs(<number>)

  Returns the absolute value of its argument.

  The number may be a floating point number, in which case a
  floating point result is returned.

  Examples:
    > say abs(4)
    You say "4"
    > say abs(-4)
    You say "4"

& ACCENT()
ACCENT()

  FUNCTION: accent(<string>, <template>)
  
  The accent() function will return <string>, with characters in it
  possibly changed to accented ones according to <template>. Both
  arguments must be the same number of characters.

  Whether or not the resulting string is actually displayed correctly
  is client-dependent. Some OSes uses different character sets than
  the one assumed (ISO 8859-1), and some clients strip these 8-bit
  characters.

  For each character in <string>, the corresponding character of
  <template> is checked according to the table below, and a replacement
  done. If either the current <string> or <template> characters aren't

ACOS()

  FUNCTION: acos(<number>[, <units>])

  Returns the arc-cosine of <number>. The value returned will be expressed in
  <units>.  <units> may be 'radians', 'degrees', or 'gradians' or just the
  first letter of any of these. By default, <units> is 'radians'.

& ADD()
ADD()

  FUNCTION: add(<number1>[,<numberN>]...)

  Returns the result of adding its arguments together. You may add up
  to 100 numbers in one add() call. <numberN> may be a floating point
  number, and a floating-point result is returned.

  Example:
    > say add(2,4)
    You say "6"
    > say add(5,3,7,-4)
    You say "11"

& ADDCOM
ADDCOM

  COMMAND: addcom <alias>=<channel>

  The alias and the channel name are case sensitive.

  Using this command, you can join a pre-existing channel by specifying the
  alias you wish to use. If the channel is named 'Public', then you must type
  it with the same case. Likewise the alias is case sensitive. If you use
  'addcom Pub=Public', then to use the channel you must type 'Pub Hello'
  instead of 'pub Hello'.

  One other thing to be careful of: adding a channel multiple times with
  different aliases. While this is possible, it is also discouraged. You
  will receive a warning when it happens.

  Example:
    >addcom pub=Public
    Channel Public added with alias pub.

  Related Topics: delcom, @clist, comlist, alias, comtitle.

& AFTER()
AFTER()

  FUNCTION: after(<string1>[,<string2>])

  This function is case sensitive.

  Returns the portion of <string1> that occurs after <string2> or after
  the first word if <string2> isn't given. If <string2> does not occur
  in <string1>, a null string is returned. If you want to return the
  portion of the string after the first space, use the rest() function
  instead.

  Examples:
    > say after(This is a test,a)
    You say " test"
    > say after(This is a test,is)
    You say " is a test"
    > say after(This is a test, nope)
    You say ""

  Related Topics: before(), first(), rest().

& ALIAS
ALIAS

  COMMAND: <channel alias> <on|off|who|message|:pose|;pose>

  The channel alias allows you to use the channel, to turn it on and off and
  check who is online. If you have forgotten what your aliases are, see the
  help for 'comlist'.

    'on'   allows you to turn an alias/channel on.
    'off'  lets you turn off that alias/channel.
    'who'  shows you who is on that channel, which the channel name appended
           to the bottom.

  You may send a message over the channel with <alias> <text>, where <text>
  is the message to be sent, or you can pose on a channel with
  <alias> :<text> or <alias> ;<text>

  Example:
    > pub Hello World!
    [Public] Player say, "Hello World!"

  Related Topics: allcom, comlist, addcom, delcom.

& ALLCOM
ALLCOM

  COMMAND: allcom <on|off|who>

  This works like using a single alias except that it does an action for
  every alias you have. You can turn every alias on, or off, or see who is
  on every channel you subscribe to.

  Example:
    > allcom who
    -- Players --
    Player1
    Player2
    -- Objects --
    -- Public --
    -- Players --
    Staff1

  are TRUE.

  Related Topics: and(), BOOLEAN VALUES, or(), not(), t().

& ANDFLAGS()
ANDFLAGS()

  FUNCTION: andflags(<object>,<list of flags>)

  This function returns 1 (TRUE) if <object> has all the flags in a specified
  list, and 0 (FALSE) if it does not. The list is specified with a single
  letter standing for each flag, like the output of the FLAGS() function. A
  '!' preceding a flag letter means "not flag".

  Thus, ANDFLAGS(me,WD) would return 1 if I were set WIZARD and DARK.
  ANDFLAGS(me,W!Dc) would return 1 if I were set WIZARD, not DARK,
  and CONNECTED.

  If a letter does not correspond to any flag, <object> doesn't have
  it, so the function returns 0. There can be an arbitrary number of
  flags. Do not put spaces between flag letters.

ANSI SUBSTITUTION
  
  The percent substitution %x<color code> can be used instead of 
  ansi(), and is more efficient. 
 
  For example, the equivalent to [ansi(rBf,Color!)] would be:
  %xr%xB%xfColor!%xn
 
  The %xn (to return to normal) is not necessary, but if it is not 
  specified the ansi color codes will continue to the end of the string.

  %x is preferred, however %c may also be used. They are equivalent.

& ARBITRARY COMMANDS
ARBITRARY COMMANDS

  You may define commands that are triggered whenever someone enters a command
  that matches the command template (wildcarding allowed).  These commands
  are called arbitrary commands, user-defined commands, or $-commands (for how
  they are defined), and they are checked for only after the check for
  single-character commands, exits, and internal commands have been performed
  and have failed (so an arbitrary command that matches 'page *' will never
  be performed).

  You define an arbitrary command by storing a string of the form
  '$<template>:<commandlist>' in an attribute of an object, then the command
  will be available to anyone who carries the object, is in the same room as
  the object, or is inside the object.  Only use user-named attributes and
  VA-VZ for arbitrary commands, as many of the predefined attributes are not
  for arbitrary commands.  <template> is the pattern to check for (it may
  contain wildcards), and <commandlist> is a semicolon-separated list of
  commands to perform.  The text that the wildcard characters matched are
  available in the variables %0 through %9.

  You can prevent individual attributes from being checked for $-commands
  with the command '@set <obj>/<attr> = no_program'.  Attributes so set
  are reported with ($) following the attribute name when examined.
  The command '@set <obj>/<attr> = !no_program' clears the flag.

  You can also match a regular expression rather than wildcards. See
  'help Regular Expressions' for details.

ATTRIBUTE OWNERSHIP

  The attributes on an object may be owned independently from the object.
  Normally, the owner of the object owns all of its attributes.
  In addition to an owner, each attribute also has a locked flag,
  set or cleared with @lock <obj>/<attr> and @unlock <obj>/<attr>.
  This flag controls whether or not the owner of the object may
  @chown the attribute to himself with @chown <object>/<attrib>,
  as well as whether or not the attribute is automatically @chowned to
  the new owner when the object is @chowned.

  You may lock and unlock attributes that you own on any object (whether
  you own the object or not), and you may @chown an attribute that you own
  to the owner of the object if it is unlocked.  The examine command
  will show you all attributes that you own on an object, even if you
  don't own the object.

BAND()

  FUNCTION: band(<number>, <number>)

  Both arguments are an integer that is treated as a bitfield. It
  performs a bitwise logical AND between these two bitfields and
  returns the resulting bitfield as an integer which can be further
  treated as an integer, a bitfield, or a logical boolean depending
  on your intentions.

     > think band(922,785)
     784

  In the above example, 922 in base 10 is equivalent to 39A in base
  16 or 0011 1001 1010 in base 2. Likewise, 785 in base 10 is the same
  as 311 in base 16 and or 0011 0001 0001 in base 2.

         0011 1001 1010 (922)

         --------------
         0011 0001 0000 (784)

  The result may be expressed as 310 in base 16 or 784 in base 10.

  So, this function is useful for testing whether a particular bit in
  the field is 'on' or 'off'. More than one bit can be tested at a
  time. If all bits are 'off', the result is zero which can also be
  interpreted as a boolean false in softcode.

  This flag suppresses the '<who> has arrived.' and '<who> has left.' messages.
  When set on a player, the messages caused by their movement are suppressed.
  When set on a location, the messages for everyone entering or leaving that
  location are suppressed.

  This flag can only be set by Wizards.

& BNAND()
BNAND()

  FUNCTION: bnand(<number1>, <number2>)

  Both arguments are an integer that is treated as a bitfield. It
  performs a bitwise logical AND between <number1> and the complement
  of <number2> which has the effect of forcing certain bits in
  <number1> off in the result.

     > think bnand(922,785)
     138

  In the above example, 922 in base 10 is equivalent to 39A in base
  16 or 0011 1001 1010 in base 2. Likewise, 785 in base 10 is the same
  as 311 in base 16 and or 0011 0001 0001 in base 2. The complement
  of 785 (specifically the one's complement) is 1100 1110 1110 in base
  2, and is a simple bitwise reversal of 1's and 0's.

          0011 1001 1010 (922)
  (BAND)  1100 1110 1110 (Complement of 785)
          --------------
          0000 1000 1010 (138)

  The result may be expressed as 08A in base 16 or 138 in base 10.

& BOGUS COMMANDS
BOGUS COMMANDS

  Bogus commands can be made using exits. For example, to make a 'sit'
  command, one could "@open sit", then "@link sit=here" (because unlinked
  exits can be stolen), "@lock sit=#0" (impossible for a room to pass a lock,
  #0 is always a room, therefore the lock always fails), and "@fail sit=You
  sit on the chair."; "@ofail sit=sits on the chair.".  Since nobody can go
  through it, it always fails. The @fail message is displayed  to the player,
  and the @ofail message (preceded by the player's name) to  everyone else.

& BOOLEAN VALUES
BOOLEAN VALUES

  There are three types of Boolean Values in MUX: BITS, BOOLEAN, and
  BOOLEAN-Z. In each case, a Boolean Value is either TRUE or FALSE, and all
  possible strings are mapped onto one of those two.

   1. The most comprehensive definition of Boolean Value is denoted simply as
      BOOLEAN. Newer functions and features use the BOOLEAN definition of a
      Boolean Value.  MUX maps the following to FALSE:

       -  Numbers (integer and floating-point) with a value of zero.
       -  The Special floating-point values of NaN, Ind, +Inf, and -Inf.
       -  Strings with zero-length.
       -  Any error message of the form "#-N <msg>".

      All other strings are understood as TRUE including negative numbers and
      dbrefs.

   2. BITS is another form of a Boolean value.  An integer can be broken down
      into BITS. Taken together, the server shows them as an integer, but
      there are functions which indirectly manipulate individual BITS.

   3. BOOLEAN-Z defines FALSE as an integer zero.  This definition still
      appears in MUX for softcode compatibility.

      Alphabetic strings are FALSE.  Everything after the decimal point in a
      floating-point number is ignored.  Dbrefs are not recognized but mapped
      to FALSE.  TRUE is then any non-zero number.

  NOTE: T() allows a BOOLEAN value to be used with a BOOLEAN-Z function, and
  Boolean Values from functions can be interpreted correctly by either BOOLEAN
  or BOOLEAN-Z definitions.

  Examples:

    not(foo) --> 0      not()    --> 1     not(-66) --> 0
    not(0)   --> 1      not(#-1) --> 1     not(#12) --> 0
    t(1)     --> 1      t(#-1)   --> 0     t(-66)   --> 1

& BOR()
BOR()

  FUNCTION: bor(<number>, <number>)

  Both arguments are an integer that is treated as a bitfield. It
  performs a bitwise logical OR which has the effect of forcing certain
  bits on in the result.

     > think bor(922,785)
     923

  In the above example, 922 in base 10 is equivalent to 39A in base
  16 or 0011 1001 1010 in base 2. Likewise, 785 in base 10 is the same
  as 311 in base 16 and or 0011 0001 0001 in base 2.

         0011 1001 1010 (922)
  (BOR)  0011 0001 0001 (785)
         --------------
         0011 1001 1011 (923)

  The result may be expressed as 39B in base 16 or 923 in base 10.

& CAND()
CAND()

  FUNCTION: cand(<boolean1>[,<booleanN>]...)

  Takes one or more BOOLEAN-Z values, and returns 1 (TRUE) if all arguments
  are TRUE. cand() evaluates its arguments from left to right until either
  all arguments evaluate to TRUE or one of the arguments evaluate to FALSE.
  This is unlike and() in that some arguments may not be evaluated.

  Related Topics: and(), candbool(), BOOLEAN VALUES, cor().

& CANDBOOL()
CANDBOOL()

  FUNCTION: candbool(<boolean1>[,<booleanN>]...)

  Takes one or more BOOLEAN values, and returns 1 (TRUE) if all arguments are
  TRUE.  candbool() evaluates its arguments from left to right until either
  all arguments return TRUE or one of the arguments returns FALSE. This is
  unlike andbool() in that some arguments may not be evaluated.

  Related Topics: andbool(), cand(), BOOLEAN VALUES, corbool().

& CANSEE()
CANSEE()

  FUNCTION: cansee(<looker>, <lookee>[,<lookee_action>])

  Only usable if the Realms package is enabled.

  CANSEE returns 1 or 0 depending on whether it's possible for the looker
  to see the lookee or not. This is useful for wizard code in the master
  room, help it decide who/what should be able to see who/what, and saves
  the softcoders the hassle of duplicating these rules in softcode.

  The third parameter is optional, but if present should be 0 for standing
  still, 1 for moving, and 2 for talking.

& CAPSTR()
CAPSTR()

  FUNCTION: capstr(<string>)

  Returns <string> with the first character capitalized.  If the first
  character is not a letter, this function returns the string unmodified.

  Example:
    > say capstr(this is a string I want capitalized)
    You say "This is a string I want capitalized"

  Related Topics: lcstr(), ucstr().

& CASE()
CASE()

  FUNCTION: case(<str>[,<pat1>,<res1>]...[,<dflt>])

  case() is like switch() but does not do wildcard matching (i.e., using *).
  In cases where wildcards are not needed, it performs marginally faster.

  Related Topics: @switch, match(), ifelse(), switch().

& CAT()
CAT()

  FUNCTION: cat(<string>[,<stringN>])

  cat returns a string made up of the contents of string1 through stringN,
  with each string separated from its neighbors by a space.

  Example:
    > say cat(this is, a test)
    You say "this is a test"
    > say cat(This is,another,test of the,CAT function)
    You say "This is another test of the CAT function"

& CEIL()
CEIL()

  FUNCTION: ceil(<number>)

  Returns the smallest integer greater than or equal to <number>.  <number>
  may be a floating point number, and an integer result is returned.

  Examples:
    > say ceil(5)
    You say "5"
    > say ceil(5.2)
    You say "6"
    > say ceil(5.8)
    You say "6"
    > say ceil(-5)
    You say "-5"
    > say ceil(-5.2)
    You say "-5"

& CENTER()
CENTER()

  FUNCTION: center(<string>, <width>[, <fill>])
 
  This function centers <string> within a <width>-sized field.

  The background of this field is specified by a repeating pattern of <fill>
  characters. The origin of this repeating pattern is at the first position
  of the field. Another way of saying this is that the repeating pattern
  starts in first position and repeats to the right. The last <fill> pattern
  may be truncated.

  By default, <fill> is a single, normal-colored space. The color of
  <string> and <fill> is maintained.

  If the visual width of <string> is longer than <width> characters, it is
  truncated to fit.
 
  Example:
    > say center(a,5,-)
    You say "--a--"
    > say center(*BAMF*,15)
    You say "    *BAMF*     "
    > say center(%xh%xrR%xgG%xbB,31,%xy--%xm+)
    --+--+--+--+--RGB+--+--+--+--+-

& CHANNEL OBJECT
CHANNEL OBJECT

  In the comsystem, you may specify a channel object for each channel.
  (@cset/object channel=<object>). See 'help @cset' for help.

  Channel objects allow you to specify a description for a channel, and
  place certain restrictions on joining, transmitting and receiving.

  NOTE: If a channel flag is set by @cpflags or @coflags, those will ALWAYS
  override the equivalent lock. The flags are set by default, so you will
  have to clear them before your locks work.

  The join lock for a channel is a normal @lock on the channel object. 
  The transmit lock for a channel is a use @lock on the channel object.  
  The receive lock for a channel is an enter @lock on the channel object. 
  The description of a channel is the @desc of the channel object.

  Related Topics: @ccreate, @create, @cset.

& CHANNELS()
CHANNELS()

  FUNCTION: channels([player])

  This function lists channels that you can see, much like @clist. If the
  argument is omitted or is 'all', then all are returned, otherwise only
  those owned by the named player are returned.

  Example:
    > say channels()
    You say, "Wizard, Staff, Guest, Public, Code"
    > say channels(#1)
    You say, "Wizard, Staff, Guest, Public"
    > say channels(me)
    You say, "Code"

CHIMERA

  The CHIMERA flag is used to denote an object who is invisible to all but
  those set CHIMERA and FAE.

& CHOWN_OK
CHOWN_OK

  FLAG: CHOWN_OK(C)  ()

  This flag, when set, allows you to transfer ownership to
  another player. To set it, you must be carrying the object. You
  also have to be in the room if you want to set this flag on rooms
  or exits.  After this flag is set, the new player may gain
  ownership of the object by using the @chown command.

& CHR()
CHR()

  FUNCTION: chr(<ord>)

  Returns a single character that corresponds to the <ord>'th position in the
  character set.

  Related Topics: ord().

& CLEARCOM
CLEARCOM

  COMMAND: clearcom

  This command will erase all channel information.

  The 'clearcom' command is equivalent to typing 'delcom <alias>' for each
  channel. It will remove you from all channels and erase your status and
  title.

  Example:
    > clearcom
    You have left channel Public.
    Channel Public deleted.
    You have left channel Staff.
    Channel Staff deleted.

  Related Topics: addcom, delcom.

& CMDS()
CMDS()

  FUNCTION: cmds(<player>)

  Returns the number of commands entered by a connected <player|port>.  If
  <player|port> is not connected or the enactor has insufficient permissions,
  then -1 is returned.

  If <player|port> is numeric, it's taken as a port number (as shown in
  SESSION).  Otherwise, it's treated as a player name.  If the named player is
  connected more than once, the first connection is returned.

  Example:
    > say cmds(me)
    You say "100"
    > say cmds(me)
    You say "101"

& COLUMNS()
COLUMNS()

  FUNCTION: columns(<list>, <width>[, <delim>[, <indent>]])

  Formats a delimited <list> into fixed-width columns.  Any element
  longer than <width> is truncated.  <indent> specifies a left margin.
  This function fits the margin and as many columns as possible into a
  78-wide screen.

    The input delimiter, <delim>, defaults to a space.
    The left margin width, <indent>, defaults to zero.

& COMALIAS()
COMALIAS()

  FUNCTION: comalias(<player>, <channel>)

  comalias() returns the alias the player uses to access the named channel.
  Wizards can retrieve the comalias for anyone. Players and objects can check
  for themselves. Objects that Inherit can check for their owners.

  Example:
    > say comalias(me,Public)
    You say "pub"

& COMLIST
COMLIST

  COMMAND: comlist

  This command displays a list of all the channels you are connected to, the
  alias you're using for the channel, whether you are 'on' or 'off' on the
  channel and what your comtitle is.

  Example:
    > comlist
    Alias     Channel            Status   Title
    pub       Public             off      Roleplay Staff

& COMMAND EVALUATION
COMMAND EVALUATION

  When you submit a command to be executed by MUX (whether by typing it in or
  by having a machine run it, the following steps are performed, in sequence.
  If the command matches something in a step, the matching actions are
  performed and the walk down the list stops.

  - The first letter of the command is checked to see if it is a single-
    character command (", :, etc).  If so, %-substitution and function
    evaluation may be performed (depending on the command), and the command
    is executed.
  - The comsystem checks for a channel alias.
  - The command is checked to see if it is the 'home' command.  If so, the
    player or object performing the command goes home.
  - The command is checked against the exits in its current room.  If one
    matches, it is performed.  If more than one matches, one is picked randomly
    from the exits for which the player passes the lock (If the player does not
    pass any locks, then the exit to be tried is picked randomly.

{ 'help command evaluation2' for more }

& command evaluation2
COMMAND EVALUATION (continued)

  - The first word of the command is checked to see if it is an internal MUX
    command.  If so, the remainder of the command is broken up into arguments,
    %-substitution and function evaluation may be performed on the (split up)
    arguments, and the command is executed.
  - %-substitution and function evaluation is performed on the command.
  - All objects in the player's inventory, all objects in the player's
    location, and the location itself are searched for $-commands that match
    the command.  All that match are performed.  The player may or may not be
    checked, depending on how the MUX is configured.
  - The commands defined in the zone tree you or your location is in.

  Note: Commands that can cause other commands to be executed (such as @wait,
  @switch, @trigger, etc) never perform substitution on their arguments, they
  leave the evaluation to the command that is to be executed.  This prevents
  most of the problems with getting objects to perform unintended commands by
  putting a ';', '}', or ',' in an argument.  The @force command is an
  exception in that it evaluates its argument, so it should be used with
  caution (preferably by never using it to pass information that someone else
  entered, use @trigger instead).

  Also, the construct '$xx *:%0' does not work (and is very dangerous
  programming), use '$xx *:@force me=%0' if you need this functionality.

& COMSYS
COMSYS

  This is the help for the MUX comsystem. Note that the channel names and
  aliases are case-sensitive. Many games are configured to have a new player
  automatically join the 'Public' channel, and a Guest join the 'Guest'
  channel. If you are a wizard, see 'wizhelp config' for the parameters
  relating to this.

  A comsys allows the various players to communicate with each other. A
  comsys can consist of one Public channel for all players, or various
  channels set aside for various groups within the game, thus allowing each
  group to communicate with the other members of that group.

  Two of the most accepted reasons for using a comsys are to allow players to
  interact with members of their group, and to provide a venue for OOC
  chatting.

& COMTITLE
COMTITLE

  COMMAND: comtitle <alias>=<title>
           comtitle[/<option>] <alias>

  This command allows you to prefix your name on a channel with a title.
  The second form contains a switch that allow you to turn on or off 
  the ability to see comtitles. <option> can be on of the following:

    on      - comtitles are shown to you.
    off     - poses are shown to you without their comtitles.

  Anonymous channels (@cset/anon) do not allow their comtitles to be
  turned off.

  Examples:
    > comtitle pub=The Great and Powerful
    Title set to 'The Great and Powerful' on channel Public.
    > pub :waves to everyone.

  a list of all options the player has permission to view.

  For boolean configuration options, config() does not return 'yes' or
  'no'.  It returns the boolean in the form compatible with BOOLEAN.

  Configuration options are determined in order by:

    - Server defaults,
    - Configuration file, and
    - @admin changes.

& CONNECTED
CONNECTED

  FLAG: CONNECTED(c)  ()

  This flag applies only to players and it shows if the
  player is connected or not. Thus, each time you are connected to
  the game, you should see the 'c' flag set, otherwise, you are DEAD!
  You cannot reset this flag, and it is used internally by the code
  for things like tabulating players for the WHO list, etc.

& CONTROL
CONTROL

  There are 6 rules to controlling objects:
   1) You control anything you own.
   2) Anything you own that has its INHERIT flag set controls anything you
      own (including you).
   3) Anything you own that does not have its INHERIT flag set only controls
      other things that you own that do not have their INHERIT flag set and
      do not control you, unless YOU have your inherit flag set.
   4) A wizard controls everything.
   5) Anybody controls an unlinked exit, even if it is locked.
   6) The object is in a part of a zone tree that you control.

  Builders should beware of 5, lest their exits be linked or stolen.

  Most of the commands for altering the database and many commands and
  functions that retrieve information only work on objects that you control.

& CONTROLS()
CONTROLS()

  FUNCTION: controls(<object>,<victim>)

  Returns 1 if <object> controls <victim>, 0 otherwise.

  Examples:
  > say controls(me,me)
  You say "1"
  > say controls(me,#1)

& CONVSECS()
CONVSECS()

  FUNCTION: convsecs(<seconds> [, <zonename>][, <precision>])

  By default, this function converts an integer (representing a count
  of seconds from Jan 01 00:00:00 1970 UTC) to a local time string --
  where local time is the time at the machine running the MUX. This
  conversion includes a timezone/daylight savings time conversion
  between UTC and the local time zone.

  If a second argument is given, it is the <zonename>:

   local - indicates that a conversion for timezone/DST of the 'local'
           server time should be applied (the default).

   utc   - indicates that no timezone/DST conversions should be applied.
           When used this way, there is a unique one-to-one relationship
           between an integer and it's corresponding text-string which
           may be useful for handling other timezones and fictional
           settings.

  <precision> determines the number of fractional seconds shown.
  By default, no fractional seconds are shown.

  Example:
    > say secs()
    You say "957558109"
    > say secs(local)
    You say "957532909"
    > say convsecs(957558109)
    You say "Fri May 05 13:21:49 2000"
    > say convsecs(957532909, utc)
    You say "Fri May 05 13:21:49 2000"

  Related Topics: convtime(), secs(), time().

& CONVTIME()
CONVTIME()

  FUNCTION: convtime(<time string> [, <zonename>][, <precision>])

  By default, this function converts a time string (of format
  [Ddd] Mmm DD HH:MM:SS YYYY) into an integer which represents a
  count of seconds since Jan 01 00:00:00 1970 UTC not including leap
  secs. Where Ddd, if given, is the day of the week. Mmm is the month
  name, DD is the day of the month, HH is the hour in 24-hour time,
  MM is the minutes, SS is the seconds, and YYYY is the year.

  Keep in mind that the year may not be exactly four characters and
  it can also be negative. This server provides a proleptic Gregorian
  calendar with a range of supported years between 27257 BC and
  30826 AD. Year 0 is 1 BC, -1 is 2 BC, ..., so 27257 BC should be
  given as -27256. This follows the astronomical conventions.

  Note: The time string can also be freeform and this function will
  attempt to parse.

  If a second argument is given, it is the <zonename>:

   local - indicates that a conversion for timezone/DST of the 'local'
           server time should be applied (the default).

   utc   - indicates that no timezone/DST conversions should be applied.
           When used this way, there is a unique one-to-one relationship
           between an integer and it's corresponding text-string which
           may be useful for handling other timezones and fictional
           settings.

  <precision> determines the number of fractional seconds shown.
  By default, no fractional seconds are shown.

  Examples:
    > say time()
    You say "Wed Jun 24 10:22:54 1992"
    > say convtime(Wed Jun 24 10:22:54 1992)
    You say "709406574"
    > say convtime(Wed Jun 24 10:22:54 1992, utc)
    You say "709381374"
    > say convtime(June 24th 1992 10:22:54.0001am Z)
    You say "709381374"
    > say convtime(Wed 24 Jun 1992 10:22:54 -0700)

& COR()
COR()

  FUNCTION: cor(<boolean1>[,<booleanN>]...)

  Takes one or more BOOLEAN-Z values, and returns 1 (TRUE) if at least one
  argument is TRUE.  cor() evaluates its arguments from left to right until
  either all arguments evaluate to FALSE or one of the arguments evaluates to
  TRUE. This is unlike or() in that some arguments may not be evaluated.

  Related Topics: BOOLEAN VALUES, cand(), corbool(), not(), or(), t().

& CORBOOL()
CORBOOL()

  FUNCTION: corbool(<boolean1>[,<booleanN>]...)

  Takes one or more BOOLEAN values, and returns 1 (TRUE) if at least one
  argument is TRUE.  corbool() evaluates its arguments from left to right
  until either all arguments evaluate to FALSE or one of the arguments
  evaluates to TRUE. This is unlike orbool() in that some arguments may not
  be evaluated.

  Related Topics: BOOLEAN VALUES, candbool(), cor(), not(), orbool(), t().

& COS()
COS()

  FUNCTION: cos(<number>[, <units>])

  Returns the cosine of <number> where <number> is expressed in <units>.
  <units> may be 'radians', 'degrees', or 'gradians' or just the first letter
  of any of these. By default, <units> is radians.

  In a circle, there are 2*pi() radians, 360 degrees, and 400 gradians.

  Examples:
    > say cos(0)
    You say "1"
    > say cos(fdiv(pi(),2))
    You say "0"
    > say cos(fdiv(pi(),4))

CRC32()

  FUNCTION: crc32(<string1>, ..., <stringN>)

  Returns the Cyclic Redundancy Check of the strings or sequences of
  strings as a positive number. The answer for the same sequence of
  strings is always the same.

  The usefulness of this number is broad, but could provide a unique
  fingerprint, checksum pattern, or high-quality hash function.

  Example:
    > think crc32(MUX)
    629126998

& CREATE()
CREATE()

  FUNCTION: create(<object>, <cost>[, <type>])

  Works the same as @create <object>, but returns the database number of
  the object created. <cost> is the cost of making the object. <type>
  is an optional parameter, 'r' for rooms, 't' for things, and 'e' for
  exits. If no <type> is specified, then a thing will be created by
  default. This is a side effect function, and should only be
  used when necessary.

& CWHO()
CWHO()

  FUNCTION: cwho(<channel> [, <select>])

  Returns a list of dbrefs from that channel. Use of this function is limited
  to wizards and channel owners. If not given, <select> defaults to 'on',
  but if given, may be any of the following:

    on  - all objects and connected players who are 'on' the channel.
    off - all objects and connected players who are 'off' the channel.
    all - all objects and players associated with the channel.

  FUNCTION: decrypt(<text>,<key>)

  Decrypts <text> using <key>. <key> should be the same one used to encrypt
  the text, and is case sensitive.

  Related Topics: encrypt().

& DEFAULT()
DEFAULT()

  FUNCTION: default(<obj>/<attr>,<default case>)

  This function returns the value of <obj>/<attr>, as if retrieved via
  the get() function, if the attribute exists and is readable by you.
  Otherwise, it evaluates the default case, and returns that.
  Note that the default case is only evaluated if the attribute does
  not exist or cannot be read.

  This is useful for code that needs to return the value of an attribute,
  or an error message or default case, if that attribute does not exist.

  Examples:
    > &TEST me=apple orange banana
    > say default(me/Test, No fruits!)
    You say "apple orange banana"
    > &TEST ME
    > say default(me/Test, No fruits!)
    You say "No fruits!"

  Related Topics: get(), get_eval(), u(), edefault(), udefault().

& DELCOM
DELCOM

  COMMAND: delcom <alias>

  Deletes <alias> from your list of channel aliases. If the <alias> was the
  only alias for the channel, then the channel has now been effectively
  removed. In order to use that channel again, you will need to re-add the
  channel with the 'addcom' command. If you only wish to have the channel
  quiet for a time, then a better command is '<alias> off'.

  Example:
    >delcom pub
    Channel Public deleted.

  Related Topics: addcom, alias, comlist, clearcom.

& DELETE()
DELETE()

  FUNCTION: delete(<string>,<first>,<len>)

  Returns <string>, but with <len> characters starting after the character
  at position <first> removed.  In other words, this function copies <first>
  characters, skips <len> characters, and then copies the remainder of the
  string.

  Example:
    > say delete(abcdefgh, 3, 2)
    You say "abcfgh"
    > say delete(Would you like coffee or perhaps tea?, 15, 18)
    You say "Would you like tea?"

& DESTROY_OK
DESTROY_OK

  FLAG: DESTROY_OK(d)  ()

  When set on an object, it allows any player to destroy
  it as long as the object is not locked against them. This is good
  for things like notes, whereby the recipient can destroy the note
  after reading it, instead of having to look for you to destroy it.
  The DESTROY_OK flag overrides the SAFE flag, so that you do not need to
  give the /override switch to @destroy to destroy a thing that is both
  DESTROY_OK and SAFE. When it is set on any object or the owner of that
  object, that object is destroyed immediately, without delay.

  Related Topics: @destroy, SAFE.

& DIE()
DIE()

  FUNCTION: die(<number of times to roll die>, <number of sides on die>)

  This function simulates rolling dice. It "rolls" a die with a given
  number of sides, a certain number of times, and sums the results.
  For example, DIE(2, 6) would roll "2d6" - two six-sided dice,
  generating a result in the range 2-12.

& DROP
DROP

  COMMAND: drop[/<switch>] <object>
           drop[/<switch>] <exit>

  The first form removes <object> from your inventory and puts it in your
  location, except for the following special cases: Dropping a STICKY thing
  sends it home, and dropping a thing in a room with a drop-to sends the thing
  to the drop-to location.

  The second form removes <exit> from your list of exits and adds it to the
  list of exits for the current location.  Anyone in the same location as
  you may then use the exit to travel to the exit's destination.  You can
  only drop exits when you own the location where you are dropping them.

  The following switch is recognized:
     /quiet   - Don't perform the @odrop/@adrop attributes on the dropped
                 object.  This switch only works if you control the object.

  'throw' is the same as 'drop'.

  Related Topics: get, @adrop, @drop, @odrop, DROP-TO, STICKY.

& DROP-TOS
DROP-TOS

  When the @link command is used on a room, it sets a drop-to location.  Any
  object dropped in the room (if it isn't STICKY) will go to that location.
  If the room is STICKY, the drop-to will be delayed until the last person in
  the room has left.

  retrieved via the get_eval() function, if the attribute exists and
  is readable by you. Otherwise, it evaluates the default case, and
  returns that. The default case is only evaluated if the attribute
  does not exist or cannot be read.

  Example:
    > &TEST me=You have lost [rand(10)] marbles.
    > say edefault(me/Test,You have no marbles.)
    You say "You have lost 6 marbles."

& ENACTOR
ENACTOR

  The enactor is the object that caused an action list to be performed.
  So, the enactor of the Ahear action list is the player or object who
  said/emoted/etc the message that matched the Listen attribute, the
  enactor of the Apay attribute is the player who gave the object money, etc.
  The enactor of an attribute that is run by a @trigger command is the
  object that ran the @trigger command.  The following substitutions can be
  performed in an action list to return information about the enactor:

    %# or [v(#)]           - Database number of the enactor
    %N/%n or [v(N)]/[v(n)] - Name of the enactor.
    %O/%o ...              - Objective pronoun for the enactor
                             (him her it them)
    %P/%p ...              - Possessive pronoun (his her its their)
    %S/%s ...              - Subjective pronoun (he she it they)

& ENTER
ENTER

  COMMAND: enter[/<switch>] <object>

  The enter command is used to enter an object. Insides of objects are best
  used for vehicles, or storage spaces when you don't have a home (or even
  as a floating home).  In order to enter an object you must either own it or
  it must have its ENTER_OK flag set, and you must also pass the object's
  EnterLock (if it has one).

  The following switch is recognized:

     /quiet   - Don't perform the @oenter/@aenter or @oefail/@aefail
                attributes on the entered object, and don't perform the
                @oxleave attribute on your current location.  This switch
                only works if you control the object being entered.

  Related Topics: leave, @aefail, @aenter, @efail, @enter, @idesc, @lock,

& ENTER_OK
ENTER_OK

  FLAG: ENTER_OK(e)  ()

  If an object or person is ENTER_OK, other players may
  enter the object or person by using 'enter <object/person>. Players
  must also have the ENTER_OK set if they wish to be able to receive
  things given to them by other players via the
  'give <player> = <object>'.

& ENTRANCES()
ENTRANCES()

  FUNCTION: entrances([<loc>[,<type>[,<low>[,<high>]]]])
 
  Returns a space-separated list of links from elsewhere to <loc>.  The
  results may include exits and drop-to's leading to <loc> as well as players
  and objects whose home is <loc>.  Unlike @entrances, entrances() does not
  report parent/child relationships.  Use children() to obtain this
  information.  <type> can be used to restrict the type of entrances returned:
  E (exit), T (thing), R (room), P (player).  There is a search cost to this
  function.  <low> and <high> can be used to indicate where to start and stop
  the search, respectively.
 
  You may only use this command on locations that you control, or else the
  results will be limited to items you can examine.

  Defaults:
    <loc>  -  your current room.
    <type> -  A (all).
    <low>  -  beginning of database.
    <high> -  end of database.
 
  Examples:
    > say entrances()           <- all links to here
    > say entrances(object)     <- all links to object
    > say entrances(here,tp)    <- everything that lives here

  Example:
    > say eq(1,-1)
    You say "0"
    > say eq(5,5)
    You say "1"
    > say eq(foo, bar)

  This function is useful in softcoded commands, especially @addcommand'ed ones.
  If the global_error_obj config parameter is not set, this will return the
  default error message. If it is, it passes <string> as if the player had typed
  it and gotten a bad command.

  Example:
    > say error()
    You say "Huh?  (Type 'help' for help.)"

    > say error(@pmit)
    You typed '@pmit'.

& ESCAPE()
ESCAPE()

  FUNCTION: escape(<string>)

  Returns <string> after adding an escape character (\) at the start of the
  string and also before each of the characters %;[]{}\ that appear in the
  string.  This prevents strings entered by players from causing undesired
  side effects when used, such as making your object perform unintended
  commands or give out information to which you have access.  Note that this
  function is only needed when the resulting string is to be passed through
  the @force command or be used as an attribute for an object (like the
  success message for a mail message object).  This function has the
  advantage over the secure() function in that the string the user sees
  after evaluating it is the same as the original string.

  Example:
    > @va me=Sneak a peek at Wiz's desc... [get(#1/desc)]
    > say escape(%va)
    You say, "\Sneak a peek at Wiz's desc... \[get(#1/desc)\]

  Note: 'say escape(Sneak a peek at Wiz's desc... [get(#1/desc)])' does not
  produce the expected result because the argument is evaluated BEFORE being
  processed by escape(), therefore the [get()] call has already been
  performed.

& EVAL()
EVAL()

  FUNCTION: eval(<object>,<attribute>)
            eval(<string>)

  The first form of the eval function works exactly like the get_eval
  function, but takes the object and attribute in two separate arguments
  instead of an obj/attr pair. It is mainly used for compatibility with
  PennMUSH 1.50. The second form simply evaluates <string>. This is normally
  done when a function is called, however, it is useful in evaluating %q and
  %v substitutions.

  Related Topics: get_eval(), get(), xget().

& EXAMINE
EXAMINE

  COMMAND: examine[/<switches>] <object>[/<wild-attrib>]

  Displays all available information about <object>.  <object> may be an
  object, 'me', or 'here'.  You must control the object to examine it,
  or it must be set VISUAL.  If you do not own the object, you will just
  see the name of the object's owner, and optionally any public
  attributes and attributes owned by you set on the object.

  If an attribute is owned by a player other than the owner of the
  object, the number of the attribute owner is shown in parentheses
  immediately following the attribute name.  Flag letters may appear in
  parentheses also, to indicate the status of the attribute.  A list of
  this flag letters is given in the references.

& EXAMINE2
EXAMINE2

  If you specify a wildcarded attribute name, then only those attributes
  that match are shown.  So, 'exam me/v?' will show all your attributes that
  start with v and are two characters long.

  The following switches are available:

     /brief  - Shows everything except attributes.

     /full   - When examining an object you don't control, show any public
               attributes set on the object in addition to the owner's name.

     /parent - Includes attributes that are not present on the object itself
               but which are inherited from the object's parent.

& EXIT()
EXIT()

  FUNCTION: exit(<object>)

  Exit returns the first exit on the list of exits in the object.  Dark exits
  are not listed, unless you own the object.  Unlike LEXITS(), this function
  does not provide information about exits in parent objects.

  Related Topics: con(), lcon(), lexits(), next().

& EXITS
EXITS

  An exit links one location to another location, providing a way to travel
  on the MUX.  Although normally used to link rooms together, exits can be
  made to and from players and objects.

  You may pick up exits that you own, and drop exits into locations that
  you own.  When you pick up or drop an exit, anyone in the exit's new
  location may use the exit and travel to its destination.  Exits may also
  be @teleported from one room to another.

  If an exit is set DARK it will not show up in the list of obvious exits in
  a room.

  If multiple exits match in name, MUX chooses between them randomly.

  Another way of creating 'variable' exits is to use the @exitto attribute.

  Related Topics: @exitto, @link, @open.

& EXP()
EXP()

  FUNCTION: exp(<power>)

  Returns the result of raising the numeric constant e to <power>.
  <power> may be a floating point number, and a floating point result
  is returned.

  Examples:
    > say exp(0)
    You say "1"
    > say exp(1)
    You say "2.718282"
    > say exp(2)
    You say "7.389056"

  Related Topics: e(), log(), ln(), power().

& EXPTIME()
EXPTIME()

  FUNCTION: exptime(<seconds>)

  This function converts seconds to a number of time elements (hours,
  minutes, seconds) that is equivalent to the given number of
  <seconds>.

  This is very similar to the writetime() function, but the elements
  are given their short names instead of long names.

  Example:
    > say exptime(45)
    You say "45s"
    > say exptime(12345)
    You say "3h 25m 45s"
    > say exptime(123456)
    You say "1d 10h 17m 36s"

  Related Topics: writetime(), singletime(), digittime(), secs(), time().

& EXTRACT()
EXTRACT()

  FUNCTION: extract(<string>, <first>, <length>[, <delim>])

  Extract returns a string of length words, starting with the first
  word. Unlike letters, the first word in a string is number 1,
  instead of 0.

  <delim> may be used to specify a delimiter other than a space.

  Examples:
    > say extract(This is a really neat example, 4, 2)
    You say "really neat"
    > say extract(Another@funky@test@for@extract, 3, 3, @)
    You say "test@for@extract"

& FAE
FAE

  The FAE flag is used to denote an object which is visible to others with
  a regular description but sees FAEDESC's and those set CHIMERA. Most
  commonly used for Changelings and those who have been Enchanted by one.

& FAILURE
FAILURE

  You fail to use a player or a thing when you cannot take it (because it's
  lock fails).  You fail to use an exit when you cannot go through it
  (because it is unlinked or locked). You fail to use a room when you fail
  to look around (because it's locked).

  Related Topics: get, look, @afail, @fail, @lock, @ofail, STRINGS.

& FDIV()
FDIV()

  FUNCTION: fdiv(<number1>,<number2>)

  Returns the floating point quotient from dividing <number1> by <number2>.
  <number> may be a floating point number, and a floating point result is
  returned.

  Examples:
    > say fdiv(15,3)
    You say "5"
    > say fdiv(16,3)
    You say "5.333333"
    > say fdiv(17,3)
    You say "5.666667"
    > say fdiv(18,3)
    You say "6"
    > say fdiv(-17,3)
    You say "-5.666667"
    > say fdiv(10,3.5)
    You say "2.857143"

  Related Topics: add(), mod(), mul(), round(), sub(), trunc().

& FILTER()
FILTER()

  FUNCTION: filter([<obj>/]<attr>, <list>[, <delim>])

  This function evaluates the contents of <attr> for each element of <list>,
  passing it in as %0.  A <delimiter>-separated list is returned of those
  elements for which the evaluation returns the value 1.

  <delimiter> may be used to specify a delimiter other than space.

  Examples:
    > &IS_ODD object=mod(%0,2)
    > say filter(object/is_odd,1 2 3 4 5)
    You say "1 3 5"

  Related Topics: u(), map(), fold()

& FILTERBOOL()
FILTERBOOL()

  FUNCTION: filterbool([<obj>/]<attr>, <list>[, <delim>])

  This function evaluates the contents of <attr> for each element of <list>,
  passing it in as %0.  A <delimiter>-separated list is returned of those
  elements for which the evaluation returns a boolean-true value.

  <delimiter> may be used to specify a delimiter other than space.

  Examples:
    > &IS_ODD object=mod(%0,2)
    > say filterbool(object/is_odd,1 2 3 4 5)
    You say "1 3 5"

  Related Topics: u(), map(), fold()

& FINDABLE()
FINDABLE()

  FUNCTION: findable(<object>,<victim>)

  Returns 1 if <object> can locate <victim>, or 0 otherwise. This checks
  wizard status of <object>, UNFINDABLE status of <victim>, and other
  related factors. If <object> would not be able to see <victim> were
  they in the same location a 0 will be returned.

& FIRST()
FIRST()

  FUNCTION: first(<string>[, <delim>])

  Returns the first word of a string, that is, everything to the left
  of the first space in the string, or the entire string if there are
  no spaces in the string.

  <delim> may be used to specify a word delimiter other than a space.

  Example:
    > say first(This is a test)
    You say "This"
    > say first(Would you like coffee, or perhaps tea)
    You say "Would"
    > say first(List&with&nonstandard&delimiters,&)
    You say "List"

& FIXED
FIXED

  FLAG: FIXED(f)  ()

  No object may teleport or go home when this flag is set. This
  flag may only be set by a wizard. If set on a player, neither they nor
  any of their objects may teleport or go home.

& FLAGS
FLAGS

  Everything in the universe of this MUX (Rooms, Exits, Things, Players,
  etc) are represented in the same way at the program level.  A room merely
  has the room flag set and a player has the player flag set.  In addition,
  flags also give objects abilities or qualities.  For instance, a wizard
  has the wizard flag set.  That is what lets the program know he may use
  wizard abilities.  An object or room may have the dark flag set. In the
  case of an object, this makes the object invisible to normal eye-sight.
  In the case of a room, the room becomes too dark to see other objects or
  players.  To get a list of the flags that are available, type '@list flags'
  or 'help flag list'. For more specific information on a particular flag,
  request help on the flag's name, as in 'help ENTER_OK'.

  FUNCTION: flags(<object>)
            flags(<object>/<attr>)

  Flags() returns a string of letters as a single word.  Each letter in this
  word represents a flag associated with <object> or with the <attr> on
  <object>.  Some flags are not revealed due to visibility and permissions.

  FLAG: FLOATING(F)  ()

  If a room is set floating, you will not be notified every 10
  minutes or so that you have a disconnected room.

& FLOOR()
FLOOR()

  FUNCTION: floor(<number>)

  Returns the largest integer less than or equal to <number>.  <number> may be
  a floating point number, and an integer result is returned.

  Examples:
    > say floor(5)
    You say "5"
    > say floor(5.2)
    You say "5"
    > say floor(5.8)
    You say "5"
    > say floor(-5)
    You say "-5"
    > say floor(-5.2)
    You say "-6"

  Related Topics: ceil(), fdiv(), mod(), round(), trunc().

& FLOORDIV()
FLOORDIV()

  FUNCTION: floordiv(<number1>,<number2>)

  Returns the integer quotient from dividing <number1> by <number2>.

  However, integer division for the case where either <integer1> or
  <integer2> is negative is defined in a specific way -- by choosing
  the largest integer that is less than or equal to the algebraic
  quotient. If <integer1> and <integer2> are the same sign, then
  idiv() and floordiv() are equivalent.

  For example, division of -9 by 5 would give -2 by this definition
  instead of -1. idiv() would return -1. floordiv() would return -2.
  The floordiv() function goes with the mod() function.

    floordiv(x,y)*y + mod(x,y) ==> x

  Examples:
    > say floordiv(15,3)
    You say "5"
    > say floordiv(16,3)
    You say "5"
    > say floordiv(17,3)
    You say "5"
    > say floordiv(18,3)
    You say "6"
    > say floordiv(-17,3)
    You say "-6"

& FOLD()
FOLD()

  FUNCTION: fold([<obj>/]<attr>, <list>[, <base-case>[, <delim>])

  This function iteratively processes a list through a function, feeding
  the result of one step into the next step as %0, passing in the next element
  from the list as %1.

  If a base case is provided, it is used as the initial %0.  If not, the first
  list element is passed as %0 and the second is passed as %1, and subsequent
  iterations proceed normally.

  <delimiter> may be used to specify a delimiter other than space, but you
  must specify a base case in order to specify the delimiter.

  Examples:
    > &REP_NUM object=[%0][repeat(%1,%1)]
    > say fold(object/rep_num,1 2 3 4 5,->)
    You say "->122333444455555"
    > &ADD_NUMS object=add(%0,%1)
    > say fold(object/add_nums,1 2 3 4 5)
    You say "15"

& FOREACH()
FOREACH()

  FUNCTION: foreach([<object>/]<attribute>,<string>[,<begin>, <end>])

  Maps a function onto a string.

  Each character in <string> has the user-defined function of the first
  argument performed on it; the character is passed to the function as
  %0. The results are concatenated. If <begin> and <end> are specified,
  only the characters between <begin> and <end> are parsed, other characters
  are concatenated as they are. This allows a rudimentary form of tokens and
  speeds up the evaluation greatly if tokenizing is your purpose.

  Examples:

    > &add_one me=[add(%0,1)]
    > say [foreach(add_one, 54321)]
    You say, "65432"

    > &add_one me=[add(%0,1)]
    > say [foreach(add_one, This adds #0# to numbers in this string,#,#)]
    You say, "This adds 1 to numbers in this string."

& FUNCTIONS
FUNCTIONS

  Functions are specialized commands used to manipulate strings and other
  input. The format for a function is of this form: [fun-name(<input>)]
  Although usually the []'s indicate an input that is optional, in this case
  they are necessary and tell the MUX that this is a function, although
  nested functions (like [first(rest(This is a nice day))] returns 'is') do
  not require more than one pair of []'s.  Nested brackets may be used when
  it is necessary to insert a function call in the middle of an argument,
  like [get(me/[get(me/vz)])], which returns the contents of the attribute
  named in the VZ attribute.

  For help on a particular function, type 'help <functionname>'.  You may
  need to include the parentheses with the function name, ie.
  'help <functionname>()'.  Type 'help function list' or '@list functions'
  for a list of the available functions.  'help function classes' will show
  a list of the functions broken down into classes.

  Related Topics: @list functions, FUNCTION CLASSES, FUNCTION LIST.

& GAGGED
GAGGED

  FLAG: GAGGED(j)  ()

  When a player is set GAGGED, they cannot speak or pose under any
  circumstances. This flag has no meaning for objects, exits, or rooms.

  Related Topics:

& GENDER
GENDER

  A player's (virtual) gender is specified in the Sex attribute.  This
  attribute controls how gender-specific pronoun substitutions are evaluated
  for the player.  If the player's Sex attribute starts with an 'M' or an 'm'
  then the player is assumed to be male,  'F', 'f', 'W', and 'w' indicate
  female, and anything else indicates neuter.

  Related Topics: SUBSTITUTIONS.

& GET
GET

  COMMAND: get[/<switch>] <object>
           get[/<switch>] <exit>
           get[/<switch>] <object>'s <sub-object>

  The first form picks up <object> from your location and adds it to your
  inventory.  It will fail if the object is locked against you, or if you
  are inside a player or object that you don't control and which isn't
  set ENTER_OK.

  The second form takes an exit from your location and adds it to you.
  Anyone inside you may then use the exit to travel to the exit's destination.
  You may take exits that you own, and exits owned by others in locations that
  you own.

  The third form takes <sub-object> from <object> and adds it to your
  inventory.  <object> must be ENTER_OK and <sub-object> must not be locked
  against you for this to work.  The lock on <object> is not checked.

{ 'help get2' for more }

& GET()
GET()

  FUNCTION: get(<object>/<attribute>)

  The get function fetches the specified attribute from the named object.
  It can be used to get attributes from objects you own, public and visual
  attributes of objects near you, and public and visual attributes other
  than the description of players wherever they may be.  If the attribute is
  not present on <object>, its parent is searched for the attribute.

  Example:
    > read me
    > say get(me/desc)

  Related Topics: get_eval(), eval(), u(), v(), xget().

& GET2
GET (continued)

  The following switch is recognized:

     /quiet   - Don't perform the @osucc/@asucc or @ofail/@afail attributes
                on the target object.  This switch only works if you control
                the object.

  <object> and <sub-object> may be either players or things.
  'take' is the same as 'get'.

  Related Topics: drop, @afail, @asucc, @fail, @ofail, @osucc, @succ,
      ENTER_OK, FAILURE, SUCCESS.

& GET_EVAL()
GET_EVAL()

  FUNCTION: get_eval(<object>/<attribute>)

  The get_eval function returns the specified attribute from the named object
  (just like the get function), except that function references and
  %-substitutions have already been performed.  In function references,
  'me' refers to the object being looked at, and %-substitutions that refer
  to the enactor (such as %n, %#, etc) refer to the object making the get_eval
  call.  If the attribute is not present on <object>, its parent is searched
  for the attribute.

  Example:
    > @va test = This is a get_eval test on %n.  The vb is [get(me/vb)]
    > @vb test = VB from test
    > @vb me = VB from me
    > say get(test/va)
    You say "This is a get_eval test on %n. The vb is [get(me/vb)]"
    > say get_eval(test/va)
    You say "This is a get_eval test on Foobar. The vb is VB from test"

  Related Topics: get(), eval(), u(), v(), xget().

& GIVE
GIVE

  COMMAND: give <player>=<amount/object>

  Gives player the specified amount of money or <object>. You can't give
  someone money if their new total would be greater than 10000 (No reason to
  get greedy).  You may also give players objects, but the other player must
  be set ENTER_OK to receive something you give.

  Related Topics: @apay, @cost, @opay, @pay, ENTER_OK.

& GOALS
GOALS

  There is no ultimate goal to this game, except to have fun.  There are
  objects and places to build, puzzles to solve, scenery to visit, and people
  to meet. There are no winners or losers, only fellow players.  Enjoy.

& GOING
GOING

  FLAG: GOING(G)  ()

  Used internally for the @destroy command, it is set on objects that are set
  to be destroyed.  In the event that a player decides before the next @dbck
  to spare the object from destruction, they can accomplish this by reseting
  the object's GOING flag.

  Related Topics: @destroy, @dbck (in wizhelp).

& GOTO
GOTO

  COMMAND: goto[/<switch>] <direction>
           goto[/<switch>] home
           <direction>
           home

  Moves you in the specified direction, assuming that the direction is not
  locked against you.  'move home' is a special command that returns you to
  your home. The word 'move' may be omitted.

  The following switch is recognized:

     /quiet   - Don't perform the @osucc/@asucc/@odrop/@adrop or @ofail/@afail
                attributes on the exit being used.  This switch only works if
                you control the exit.

  'move' is the same as 'goto'.

& GRAB()
GRAB()

  FUNCTION: grab(<list>, <pattern>[, <delim>])

  This function matches <pattern> against each word in <list>, returning the
  first word that matches.  If no words match, then an empty string is
  returned.  The match is not case-sensitive, and wildcard characters are
  permitted in <pattern>.  <delim> may be used to specify a list delimiter
  other than a space.

  Examples:
    > say grab(This is a new test,?e*)
    You say "new"
    > say grab(Holodeck:#10~Airlock:#58~Dorm:#12~Brig:#83,Airlock:*,~)
    You say "Airlock:#58"

  Related Topics: graball(), LISTS, member(), match(), regrab().

& GRABALL()
GRABALL()

  FUNCTION: graball(<list>, <pattern>[, <delim>])

  This function matches <pattern> against each word in <list>, returning the
  all words that match.  If no words match, then an empty string is returned.
  The match is not case-sensitive, and wildcard characters are permitted in
  <pattern>.  <delim> may be used to specify a list delimiter other than a
  space.

  Examples:
    > say graball(This is a test of a test,test)
    You say "test test"
    > say graball(This is testing a test,tes*)
    You say "testing test"

  Related Topics: grab(), LISTS, regrab(), regraball().

& GREP()
GREP()

  FUNCTION: grep(<object>,<attrs>,<pattern>)

  This function returns a list of attributes on <object> containing
  <pattern>.  <attrs> is a wildcard pattern for attribute names to
  search; if you want to search all attributes, use "*".

  Parsing _does_ occur before this function is invoked. Therefore,
  "special" characters will need to be escaped out.  <pattern> is
  NOT wildcard matched.

  This function is case-sensitive. grepi() is a case-insensitive version.

  Related Topics:

& GREPI()
GREPI()

  FUNCTION: grepi(<object>,<attrs>,<pattern>)

  This function works exactly like grep, but is case-insensitive.

  Related Topics: grep()

& GT()
GT()

  FUNCTION: gt(<integer1>,<integer2>)

  Takes two integers, and returns 1 if and only if <integer1> is greater than
  <integer2>, and 0 otherwise.  Warning: passing anything but integers will
  produce unexpected results, as non-numeric strings usually are treated
  as numeric 0.

  Example:
    > say gt(4,5)
    You say "0"
    > say gt(5,5)
    You say "0"
    > say gt(6,5)
    You say "1"
    > say gt(foo, bar)
    You say "0"

  Related Topics: lt(), lte(), gte(), eq(), neq().

& GTE()
GTE()

  FUNCTION: gte(<integer1>,<integer2>)

  Takes two integers, and returns 1 if and only if <integer1> is greater than
  or equal to <integer2>, and 0 otherwise.  Warning: passing anything but
  integers will produce unexpected results, as non-numeric strings usually are
  treated as numeric 0.

  Example:
    > say gte(4,5)
    You say "0"
    > say gte(5,5)
    You say "1"
    > say gte(6,5)
    You say "1"
    > say gte(foo, bar)
    You say "1"

  Related Topics: lt(), lte(), gt(), eq(), neq().

& HALTED
HALTED

  FLAG: HALTED(h)  ()

  While this flag is set, the object cannot perform any MUX
  actions, listen, be triggered, etc.

  Related Topics:

& HASATTR()
HASATTR()

  FUNCTION: hasattr(<object>, <attribute name>)

  Returns 1 if the object has the named attribute, and 0 if it does
  not. If the object does not exist or the player does not have the
  ability to examine the object, #-1 will be returned.

  Hasattr() doesn't check for attributes inherited from parent
  objects. Use hasattrp() for that.

  Related Topics:

& HASATTRP()
HASATTRP()

  FUNCTION: hasattrp(<object>, <attribute name>)

  Returns 1 if the object or its parent has the named attribute,
  and 0 if it does not. If the object does not exist or the player
  does not have the ability to examine the object, #-1 will be returned.

  Use hasattr() to check for attributes without checking parents.

  Related Topics:

& HASFLAG()
HASFLAG()

  FUNCTION: hasflag(<object>[/<attribute>],<flag>)

  Returns true if object <object> has the flag named <flag> set on it. You
  may not be able to retrieve information for objects that you do not own.

  When an <attribute> is given, the following <flag> values can be used.

    const, no_command, dark, god, hidden, html, no_inherit, locked, no_parse,
    regexp, visual, and wizard.

  Example:
    > say hasflag(me, wizard)
    You say "0"
    > say hasflag(me, connect)
    You say "1"

  Related Topics:

& HASPOWER()
HASPOWER()

  FUNCTION: haspower(<object>,<power>)

  Returns true if object <object> has the power named <power> set on it.
  You may not be able to retrieve information for objects that you do not
  own.

  Example:
    > say haspower(me, announce)
    You say "0"
    > say hasflag(me, extended_who)
    You say "1"

  Related Topics:

& HASQUOTA()
HASQUOTA()

  FUNCTION: hasquota(<object>, <quota>[, <type>])

  Returns true if object <object> has enough quota to build anything
  requiring <quota> quota. If <type> is given, the function returns true if
  there is enough quota to build a <type> object requiring <quota> quota.

  Currently, MUX doesn't support typed quotas, but if it did, a type-specific
  query may return true while a generic query would return false.

  Example:
    > say hasquota(me, 100)
    You say "0"
    > say hasquota(me, 1)
    You say "1"

  Related Topics: @quota

& HASTYPE()
HASTYPE()

  FUNCTION: hastype(<object>, <type>)

  Returns 1 if the object is of the named type, otherwise 0.
  Valid types are: ROOM, EXIT, PLAYER, THING.
  If an invalid type is given, #-1 is returned.

  Related Topics:

& HAVEN
HAVEN

  FLAG: HAVEN(H)  ()

  @set here=haven;@set me=haven. If a location is HAVEN, you
  cannot kill in that location.  The HAVEN flag no longer blocks pages or
  @pemits, use @lock/page instead.

  Related Topics: @lock/page.

& HEAD
HEAD

  FLAG: HEAD(?)  ()

  This is another marker flag, for faction heads and the like. As
  with STAFF, no powers come with it, it is purely a marker.

  Related Topics:

& HERE
HERE

  The word 'here' refers to the room you are in (if you are inside an object,
  it refers to the object that you are in, not the room that the object is
  in).  For example, to rename the room you are in (if you control it), you
  could enter '@name here= <new name>'.

& HOME()
HOME()

  FUNCTION: home(<object>)

  Returns the object's home.

  Example:
    > exam me
    Mortal(#226Pc)
    Type: PLAYER Flags: CONNECTED
    Desc:Just a plain, old boring Mortal. You know.
    Owner: Mortal  Key: VA:foobar Clams: 920
    Last:Thu Dec 19 08:57:21 1991
    Home: Mortal's Room(#367R)
    Location: The Town Square
    > say home(me)
    You say "#367"

  Related Topics:

& HOMES
HOMES

  Every thing or player has a home.  This is where players when they go home,
  or things with the STICKY flag set go when dropped.  Homes are set with the
  @link command. A thing's home defaults to the room where it was created, if
  you control that room, or your home. You can link an exit to send players
  home with '@link <dir>=home'.  Drop-tos can also be set to 'home'.

  Related Topics: @link, DROP-TO, STICKY.

& HOST()
HOST()

  FUNCTION: host(<player|port>)

  Returns the hostname for <player|port> as seen on the SESSION report.

  If <player|port> is numeric, it's taken as a port number.  Otherwise, it's
  treated as a player name.  If the named player is connected more than once,
  the first connection is returned.

  Related Topics: SESSION.

& HSS
HSS

  The HSS flag denotes someone who can see through certain levels of
  invisibility. They must have the HSS_LEVEL attribute set. If they have
  this flag and attribute set they will see anyone with a lower OBF_LEVEL
  then their HSS_LEVEL attribute, they will also see the OBFDESC if it
  is present, showing the invisible character's true appearance. However,
  if HSS_LEVEL is equal to OBF_LEVEL then there is a random chance that
  they will see through the invisibility.

  Related Topics: OBF

& IABS()
IABS()

  FUNCTION: iabs(<integer>)

  Returns the absolute value of its argument.

  Examples:
    > say iabs(4)
    You say "4"
    > say iabs(-4)
    You say "4"
    > say iabs(0)
    You say "0"

  Related Topics: abs(), isign(), sign().

& IADD()
IADD()

  FUNCTION: iadd(<number1>[,<numberN>]...)

  Returns the result of adding its integer arguments together. You may
  add up to 100 numbers in one iadd() call. Similar to add() except
  that the addition is done with integer math.

  Example:
    > say iadd(2,4)
    You say "6"
    > say iadd(5,3,7,-4)
    You say "11"

  Related Topics: add(), dec(), idiv(), imul(), inc(), isub(), mod(),
            mul(), sub().

& IDIV()
IDIV()

  FUNCTION: idiv(<number1>,<number2>)

  Returns the integer quotient from dividing <number1> by <number2>.

  However, integer division for the case where either <integer1> or
  <integer2> is negative is defined in a specific way -- by choosing
  the smallest integer that is greater than or equal to the algebraic
  quotient. If <integer1> and <integer2> are the same sign, then
  idiv() and floordiv() are equivalent.

  For example, division of -9 by 5 would give -1 by this definition
  instead of -2. idiv() would return -1. floordiv() would return -2.

    idiv(x,y)*y + remainder(x,y) ==> x

  Examples:
    > say idiv(15,3)
    You say "5"
    > say idiv(16,3)
    You say "5"
    > say idiv(17,3)
    You say "5"
    > say idiv(18,3)
    You say "6"
    > say idiv(-17,3)
    You say "-5"

  Related Topics: fdiv(), floordiv(), iadd(), imul(), isub(), mod(),
                  remainder().

& IDLE()
IDLE()

  FUNCTION: idle(<player|port>)

  Returns the number of seconds that <player|port> has been idle.  If
  <player|port> is not connected then -1 is returned.

  If <player|port> is numeric, it's taken as a port number (as shown in
  SESSION).  Otherwise, it's treated as a player name.  If the named player is
  connected more than once, the smallest idle time is returned.

  Example:
    > WHO

    Player Name          On For Idle  Doing
    Wizard                00:04   1m
    Mortal                00:11   0s
    Evinar                00:12   6m
    3 Players logged in.
    > say idle(wiz)
    You say "6"
    > say idle(e)
    You say "371"
    > say idle(frobozz)
    You say "-1"

  Related Topics: WHO, conn(), lwho().

& IFELSE()
IFELSE()

  FUNCTION: ifelse(<expression>,<true string>,<false string>)
                if(<expression>,<true string>[,<false string>])

  This function returns <true string> if BOOLEAN <expression> is TRUE,
  <false string> otherwise. Much more efficient than an equivalent switch().
  It can also return different messages based on whether <expression> is
  nothing or contains text.  if() does the same thing, but the third,
  <false string> argument is optional.

  Example:
    > think ifelse(v(test),Test exists!,Test doesn't exist.)
    Test doesn't exist.

  Related Topics: BOOLEAN VALUES, switch().

& ILEV()
ILEV()

  FUNCTION: ilev()

  Returns the nesting level of iter(), list(), and parse() functions. Outside
  of any iterator, ilev() returns -1. The first level is indicated by 0, the
  second by 1, etc.

  Related Topics: iter(), list(), parse().

& IMMORTAL
IMMORTAL

  FLAG: IMMORTAL(i)  ()

  Objects set immortal cannot be killed and don't use up money.
  Only settable by wizards.  This is useful when an object's location
  shouldn't be changed by Joe Player, but you don't want to have to relink it
  to its current location whenever it moves.

  Related Topics:

& IMUL()
IMUL()

  FUNCTION: imul(<number1>[,<numberN>]...)

  Returns the result of multiplying its integer arguments together.
  Similar to mul() except that the multiplication is done with
  faster integer math.

  Examples:
    > say imul(3,5)
    You say "15"
    > say imul(3,5,-2)
    You say "-30"

  Related Topics: add(), fdiv(), iadd(), idiv(), isub(), mod(), mul(),
            round(), sub(), trunc().

& INC()
INC()

  FUNCTION: inc(<number>)

  Returns <number> plus 1. Faster and more efficient than
  add(<number>,1). Decimal places are truncated.

  Related Topics: add(), dec(), iadd(), isub(), sub().

& INDEX()
INDEX()

  FUNCTION: index(<list>,<character>,<first>,<length>)

  This function is similar to EXTRACT(), except that an item in the
  list may be more than one word; instead of a space being used to
  separate items in the list, <character> is used. The function returns
  <length> items starting from that in the <first> position. Trailing
  spaces are trimmed. The comma cannot be used as the <character> separator.

  Example:

& INHERIT
INHERIT

  FLAG: INHERIT(I)  ()

  Previously, Wizard-owned objects had wizard powers.  This was
  a problem in many cases, so that behavior has changed.  Now, only Wizard
  objects or Wizard-owned Inherit-set objects have wizard powers.  Only
  players can set the Inherit flag, and the Inherit flag is reset during
  @chown.  If a player is set Inherit, all his stuff is assumed to be
  inherit, so his objects can control him.  If a player is NOT Inherit,
  his stuff does NOT control him.  (i.e. cannot @force him.)  This flag
  is not especially useful for non-wizards.

& INSERT()
INSERT()

  FUNCTION: insert(<list>, <pos>, <word>[, <delim>])

  This function inserts a word into <list> so that the word becomes the
  <pos>'th element of the list, and all subsequent list elements are moved
  down.  This means that it appears between the <pos-1>'th and <pos>'th
  elements of the original list.  This function may also be used to append
  a word to a list.

  <delim> may be used to specify a delimiter other than a space.

  Examples:
    > say insert(This is a test, 4, new)
    You say "This is a new test"
    > say insert(Yet@Another@List, 3, Funky, @)
    You say "Yet@Another@Funky@List"

& INUM()
INUM()

  FUNCTION: itext(<n>)
            inum(<n>)
            ilev()

  These functions, when called within an iter() or parse(), return the
  equivalent of ## (itext) or #@ (inum), with reference to the nth more
  outermost iter(), where n=0 refers to the current iter(), n=1 to an iter()
  in which the current iter() is nested, etc.

  Unlike the ## and #@ substitutions which are substituted in the evaluation
  string before it is evaluated, itext(), inum(), and ilev() substitute their
  values as part of evaluation. In this way, the use of these functions is
  safer than the ## and #@ substitutions and is therefore preferred.
   
  > say [iter(red blue green,iter(fish shoe, #@:##))]
  You say, "1:red 1:red 2:blue 2:blue 3:green 3:green"
   
  > say [iter(red blue green,iter(fish shoe, [inum(1)]:[itext(1)]))]
  You say, "1:red 1:red 2:blue 2:blue 3:green 3:green"

& ISDBREF()
ISDBREF()

  FUNCTION: isdbref(<string>)

  This function will return 1 if the string passed to it is a valid dbref.
  To be a valid dbref the string must begin with '#' and be followed by an
  integer.  Also, the dbref must exist in the current database as a valid
  object.  If the object fails either of these criteria, then a 0 is
  returned.

  Example:
     > say isdbref(#-1)
     You say "0"
     > say isdbref(#1)
     You say "1"
     > say isdbref(This is not a dbref)

  FUNCTION: isint(<string>)

  This function will return 1 (TRUE) if the argument is a valid integer and 0
  (FALSE) if it is not. Integers have an optional leading + or - sign followed
  by digits only.

  Example:
     > say isint(22223.0000)
     You say "0"
     > say isint(+77)
     You say "1"
     > say isint(22 L)

  0 (FALSE) otherwise. This definition of a number includes scientific
  notation as well as a certain case-insensitive 'special words': NaN, -Inf,
  +Inf, and Ind.

  You can test more restrictively with israt() or isint().

  Example:

  but excludes scientific notation and 'special words': NaN, -Inf, +Inf, and
  Ind.

  You can test more restrictively with isint() and more inclusively with
  isnum().

  Example:
     > say israt(22223.0000)
     You say "1"
     > say israt(+77)

& ITEMIZE()
ITEMIZE()

  FUNCTION: itemize(<list>[, <delim>[, <conj>[, <punc>]]])

  This function takes a <delim>-separated <list>, and:

   If there's just one element, return it.
   If there's two elements, return <e1> <conj> <e2>
   If there's more than two, return <e1><punc> <e2><punc> ... <conj> <en>

  The default <conj> is "and", default <punc> is ",", and default <delim> is
  space.

  Examples:
    > say [itemize(eggs)] * [itemize(eggs bacon)]
    You say, "eggs * eggs and bacon"
    > say [itemize(eggs bacon spam)]
    You say, "eggs, bacon, and spam"
    > say [itemize(eggs bacon spam, ,&,;)]
    You say, "eggs; bacon; & spam"

& ITEMS()
ITEMS()

  FUNCTION: items([<object>])

  items() returns the number of items that the stack of the calling object
  contains. If <object> is specified and you control it, then it returns the
  number of items in the stack of that object.

  Related Topics: lstack(), empty(), peek(), pop(), push(), OBJECT STACK.

& ITER()
ITER()

  FUNCTION: iter(<list>,<eval>[,<input delim>[,<output delim>]])

  <list> is a <input delim>-separated list of strings (e.g., A B C).  <eval>
  is a string that is to be evaluated once for each item in <list> replacing
  the special symbol ## with the corresponding item from <list> and the symbol
  #@ with the position within the list being iterated. Remember that <eval> is
  evaluated after ## and #@ are substituted.  For this reason, itext() is
  preferred over ##, and inum() is preferred over #@.

  An <output delim>-separated list of the results of these evaluations is
  returned to the caller.  The effect is very similar to @dolist except that
  the results are made into a list and returned instead of executed.

  In addition to any single character, <output delim> can also be the null-
  delimiter, @@, or a newline, %r. By default, input and output delimiters are
  both space.

  Examples:
    > say iter(This is a test,strlen(##))
    You say "4 2 1 4"
    > say iter(lnum(10),mul(mul(##,##),10))
    You say "0 10 40 90 160 250 360 490 640 810"
    > say iter(lcon(me),[name(##)]..[money(##)])
    You say "test..1 t1..1 radio..1 The Wizard's Pointy Hat..1"
    > say iter(Was it a cat I saw,[words(##)] #@,s)
    You say "1 1 4 2 1 3"

& ITEXT()
ITEXT()

  FUNCTION: itext(<n>)
            inum(<n>)
            ilev()

  These functions, when called within an iter() or parse(), return the
  equivalent of ## (itext) or #@ (inum), with reference to the nth more
  outermost iter(), where n=0 refers to the current iter(), n=1 to an iter()
  in which the current iter() is nested, etc.

  Unlike the ## and #@ substitutions which are substituted in the evaluation
  string before it is evaluated, itext(), inum(), and ilev() substitute their
  values as part of evaluation. In this way, the use of these functions is

KILL

  COMMAND: kill <player> [=<cost>]

  Attempts to kill the specified player. Killing costs <cost> coins, which
  gives you a <cost>% chance of killing the player. Thus, spending 100
  coins always works (except against wizards and immortals, who can never be
  killed). Players cannot be killed in rooms which have been set HAVEN or
  which they control.  If you don't specify a cost, the default is 10 (for a
  10% chance of success).  The player, if killed, receives <cost>/2 coins in
  insurance.

& LIST()
LIST()

  FUNCTION: list(<list>, <eval>[, <delim>])

  This function is exactly like iter() but serves a specialized purpose:
  MUX has a buffer limit, and for things like lists of players, iter() can
  quickly become inadequate, since the output is cut off before the listing
  is finished. The normal way to handle this is to use a @dolist/@pemit
  combination, but that takes many queue cycles. list() takes <list>,
  <eval>, and an optional delimiter, and evaluates them exactly like
  iter(). The difference is the output: iter() produces a space-separated
  list, while list() outputs each list item on a new row of the screen.

  NOTE: This is a side effect function. It does not return anything,
  instead, it prints its output directly to the screen of the player causing
  the function to be evaluated. Since it does this, it is not hampered by
  the buffer limit.

  Related Topics: iter(), @dolist, parse().

& LISTENING
LISTENING

  Thee are two ways to listen for something in a room. The easiest way
  is to use a combination of @listen and @ahear/@aahear/@amhear. The
  second way is to use a "^" pattern in an attribute, similar to the way
  "$" is used for user-defined commands. The attribute takes the form:
  '^<pattern>:<action>'.

  The ^-pattern check is only performed on objects with their MONITOR flag
  set.  The criterion for triggering a pattern-listen is the same as that for
  triggering an @ahear - the object cannot trigger its own listen patterns.
  All matching attributes have their <action>s performed, not just the first.
  Also, attributes with the no_command flag set are not checked for ^-patterns,
  and neither are objects' parents.

  Example:
    > @va test = ^* says "foo *":say I got a foo with %1!.
    Set.
    > @set test=monitor
    test grows ears and can now hear.
    > say foo bar
    You say "foo bar"
    test says "I got a foo with bar!."

  Related Topics: @ahear, @listen, @set.

& LISTS
LISTS

  A list is a string, usually stored in an attribute (currently any of the
  va-vz attributes), which is a series of words, separated by one or more
  spaces.  The following would be a list (denoted on the ends by ', which is
  not actually in the string): 'one two three four five'.  The functions
  first(), rest(), cat(), member(), and remove(), all work on lists.

  Related Topics: cat(), first(), member(), remove(), rest().

& LIT()
LIT()

  FUNCTION: lit(<string>)

  This function returns the string literally - without even squishing
  spaces, and without evaluating *anything*. This can be useful for
  writing ASCII maps with spaces or whatever.

  It can be a bit tricky to get a literal string with spaces into an
  attrib, however, since spaces are usually squished in setting an
  attribute. This example illustrates how to make it work:

  Example:
    > @va me=$test: think {[lit(near       far)]}
    Set.
    > ex me/va
    VA [#1]: $test: think {[lit(near       far)]}
    > test
    near       far

  Leaving out the {}'s will not work in the above.

& LJUST()
LJUST()

  FUNCTION: ljust(<string>, <width>[, <fill>])

  This function left-justifies <string> within a <width>-sized field. That
  is, it positions <string> visually in the left-most part of a
  <width>-sized field.

  The background of this field is specified by a repeating pattern of <fill>
  characters. The origin of this repeating pattern is at the first position
  of the field. Another way of saying this is that the repeating pattern
  starts in first position and repeats to the right. The last <fill> pattern
  may be truncated.

  By default, <fill> is a single, normal-colored space. The color of
  <string> and <fill> is maintained.

  If the visual width of <string> is longer than <width> characters, it is
  truncated to fit.

  Examples:
    > say -[ljust(foo,6)]-
    You say "-foo   -"
    > say %r0[ljust(foo,6)]7%r01234567
    You say "

  FUNCTION: lnum(<number1>[,<number2>][,<sep>])

  If only given one argument, this function returns a list of numbers from
  0 to <number1>-1. If <number1> less than 1, nothing is returned.

  If given at least two arguments, this function returns a list of numbers
  from <number1> to <number2>. If <number2> is less than <number1>, the list
  will be in descending order, otherwise, the list will be in ascending order.
  Negative integers are valid.

  <sep> is used as the separator character, if given.

  Examples:
    > say lnum(5)
    You say "0 1 2 3 4"
    > say lnum(3,7)
    You say "3 4 5 6 7"
    > say lnum(4,-2,|)
    You say "4|3|2|1|0|-1|-2"
    > say lnum(2,6,@@)
    You say "23456"

& LOC()
LOC()

  FUNCTION: loc(<object>)

  Returns the number of the location where <object> is.  You must either
  control the object or be nearby for it to work.  When used on an exit it
  returns the destination of the exit.  You can also use loc() to find the
  location of players that are not set UNFINDABLE.

  Example:
    > look
    Mortal's Room(#367R)
    A bare room with nothing in it but a bed and a chair.
    Contents:
    hat(#368)
    > say loc(me)
    You say "#367"
    > enter hat
    hat(#368)
    Contents:
    cat(#325)
    > say loc(me)
    You say "#368"
    > say loc(here)
    You say "#367"

& LOCALIZE()
LOCALIZE()

  FUNCTION: localize(<expression>)

  This function evaluates <expression> using its own private copy of the
  global r-registers.  That is, the global registers are saved before
  <expression> is evaluated and restored afterwards.

  This allows the <expression> to alter the r-registers without affecting the
  softcode outside the localize() invocation.

  In many ways, localize() is the same as ulocal() except that <expression>
  is given as an argument instead of stored on an attribute.

  Related Topics: ulocal(), objeval(), s().

& LOCATE()
LOCATE()

  FUNCTION: locate(<looker>,<string>,<where>)

  The locate function is used to look for an object from the perspective of
  <looker> (You must own <looker>).  The database number of the item that
  is found is returned.  The <where> parameter specifies a list of places to
  look, from this list:
    a    - Look for absolute references (#<number>)
    c    - Look for exits carried by <looker> (and by <looker>'s parents).
    e    - Look for exits in <looker>'s location (and the location's parents).
    h    - Look for 'here', which matches <looker>'s location.
    i    - Look in <looker>'s inventory.
    m    - Look for 'me', which matches <looker>.
    n    - Look for <looker>'s neighbors (other objects in the same location).
    p    - Look for player names prefixed by a '*'
    *    - Look for everything in the above list.

{ 'help locate2' for more }

& LOCATE2
LOCATE() (continued)

  You may also specify qualifiers in <where> to help resolve possible
  ambiguities:
    E    - Prefer exits over other types.
    L    - Prefer unlocked exits over locked exits.
    P    - Prefer players over other types.
    R    - Prefer rooms over other types.
    T    - Prefer things over other types.
    V    - Report "Can't find..." and "Which one..." errors to <looker>.
    X    - Select randomly if search finds multiple matches.

  If nothing matches, the value #-1 is returned.  If more than one thing
  of the preferred type matches, but nothing matches exactly, the value #-2
  is returned, except if the X qualifier was specified in which case one is
  chosen at random.  If more than one thing exactly matches, one is chosen
  at random.  If you specify more than one type preference (E, P, R, or T),
  then the last one entered is the one that is obeyed.  The default is for
  no type to be preferred.

LOGOUT

  COMMAND: logout

  Disconnects you from your character without breaking the network connection
  to the game.  You may then log in to another character.

  Related Topics: quit.

& LOOK
LOOK

  COMMAND: look[/<switches>] [<object>]

  Displays the description of <object>, or the room you're in if you don't
  specify an object.  Specifying object as <name> or #<dbref> or 'me' or
  'here' is legal.  You can also use look to look at objects held by other
  people, just use 'look <person>'s <object>'.

  You may use the /outside switch to look at the location of your current
  location (useful if you are inside a vehicle or other object).  You may
  also look at other objects in the 'outer' location, but you may not
  use the possessive form with the /outside switch (ie: "look/outside
  <person>'s <object>" won't work).

  'read' is the same as 'look'.

& LOOPING
LOOPING

  Looping in an object can have its good parts and its bad parts.  The good
  part is when you activate part of a program multiple times to exhaustively
  perform an operation.  This is usually done by:
     @va object =  <list of commands>;@trigger me/vb
     @vb object =  @switch <test> = <false>,@trigger me/va,<otherwise go on>

  Looping can be a problem when it goes on without stopping.  The @ps command
  can be used to see if you are looping.  Beware!  A looping machine that
  isn't @halt'ed will drain your money supply while you are away!

& LOR()
LOR()

  FUNCTION: lor(<list of booleans>[,<delim>])

  Takes a list of one or more BOOLEAN-Z values, and returns 1 (TRUE) if any
  of its elements are TRUE.

  Examples:

    You say, "1"
    > say [lor(1|1,|)]
    You say, "1"

& LPARENT()
LPARENT()

  FUNCTION: lparent(<object>)

  This function returns a list consisting of the object's db# (as per
  num()), the db# of its parent, grandparent, great-grandparent, etc.
  The list will not, however, show parents of objects which the player
  is not privileged to examine.

& LPOS()
LPOS()

  FUNCTION: lpos(<string>, <character>)

  This function returns a list of the positions that <character> occupies
  in <string>, with the first character of the string being 0. (Note that
  this differs from the pos() function, but it consistent with functions
  such as mid().)

  If <character> is null, a space is assumed.

  Example:
    > say lpos(a-bc-def-g,-)
    You say "1 4 8"

& LRAND()
LRAND()

  FUNCTION: lrand(<lower>,<upper>,<count>,[,<output delim>])

  Returns a list with <count> elements separated by <output delim> (or
  a space if not specified) of random numbers between <lower> and
  <upper>.

  For instance, 'lrand(3, 6, 5)' would generate five random numbers
  in the range 3 - 6 (i.e., 3, 4, 5, or 6), such as '4 6 3 5 6'.

  Related Topics: die(), lnum(), pickrand(), rand(), shuffle()

& LROOMS()
LROOMS()

  FUNCTION: lrooms(<loc> [,<depth> [,<all>]])

  Returns a space-separated list of the rooms connected to <loc> taking
  into account parentage and permissions.

  <depth> defaults to adjacent rooms (value of 1), but a larger value
  would include rooms that are correspondingly further away.

  <all> is a flag that controls whether all traversed rooms or whether
  only the rooms at the perimeter are reported. By default, all rooms
  are returned.

  Example:
    > look here
    The Town Square
    You are in the town square.  All around you .....
    Obvious exits:
    foo  up  southeast  sw  north
    > say lrooms(here,1)

  <object> is not specified, then it returns the stack of the executing
  object.

  Related Topics: push(), pop(), peek(), empty(), items(), OBJECT STACK.

& LT()
LT()

  FUNCTION: lt(<integer1>,<integer2>)

  Takes two integers, and returns 1 if and only if <integer1> is less than
  <integer2>, and 0 otherwise.  Warning: passing anything but integers will
  produce unexpected results, as non-numeric strings usually are treated
  as numeric 0.

  Example:
    > say lt(4,5)
    You say "1"
    > say lt(5,5)
    You say "0"
    > say lt(6,5)
    You say "0"

  equal to <integer2>, and 0 otherwise.  Warning: passing anything but integers
  will produce unexpected results, as non-numeric strings usually are treated
  as numeric 0.

  Example:

  Related Topics: lt(), gte(), gt(), eq(), neq().

& LWHO()
LWHO()

  FUNCTION: lwho([<boolean>])

  Returns a list of the db numbers of connected players.  This returns what
  a 'WHO' or 'DOING' would return.  This takes an optional boolean value.
  '0' is the default, and '1' returns the player list in the form dbref:port.
  Only wizards may use the port option.

  Example:
    > WHO
    Player Name          On For Idle  Doing
    Mortal                00:11   0s

& MAIL()
MAIL()

  FUNCTION: mail(<mail message #>)
             mail(<player name>)
             mail(<player>, <mail message #>)
             mail()

  The first form returns a message corresponding to that mail message
  number in your MUX mailbox. This function can be used to forward
  mail, or as a way to simply transfer mail messages to attributes
  on an object.

  The second form returns three numbers, corresponding to the number of
  read, unread, and cleared messages <player> has.
  The third form returns <player>'s <mail message #>. It works like
  the first form except it applies to another player.
  The last form returns the number of messages the evaluating player has.
  Only wizards can use the second and third forms of the function
  on other players.

  Related Topics: @mail, mail-reading.

& MAIL-ADMIN
MAIL-ADMIN

  The @mail command can also take the following switches:

    @mail/stats [<player>]    --  Basic mail statistics.
    @mail/dstats [<player>]   --  Also provides read/unread count.
    @mail/fstats [<player>]   --  Does all that, plus gives space usage.

    @mail/debug <action>[=<player>]
    @mail/nuke

  Only wizards may stats players other than themselves. The mail statistics
  commands are computationally expensive, and thus are subject to "daytime"
  restrictions. They also cost the same as a @find (100 credits).

  The /debug switch does sanity checking on the mail database, and may only
  be used by a wizard. "@mail/debug sanity" just does the check; the command
  "@mail/debug clear=<player name or dbref number>" wipes mail for an object.
  "@mail/debug fix" attempts to repair problems noted in the sanity check.

  The /nuke switch destroys the post office, erasing all @mail everywhere.
  It may only be used by a wizard.

  Also, admin may set the @amail attrib on their char.  When somebody sends
  you mail, it will trigger that attrib if it exists.

& MAIL-EXAMPLES
MAIL-EXAMPLES

  Here is an example of mailing a player, where is the player will be "bob",
  and sending the mail.

  > @mail bob = The MUX              - This is the Subject line.

  Sending mail to player 'Bob'
  > -Hi bob.                         - This is where you will enter the body
                                       of the message.
  Text Added.
  > @send                            - Basically, sends the @mail.

  MAIL: You sent your message to 'Bob'.

& MAIL-FOLDERS
MAIL-FOLDERS

  The MUX mail system allows each player 16 folders, numbered from
  0 to 15. Mail can only be in 1 folder at a time. Folder 0 is
  the "inbox" where new mail is received. Most @mail commands
  operate on only the current folder.

  @mail/folder
        This commands lists all folders which contain mail, telling
        how many messages are in each, and what the current folder is.

  @mail/folder <folder#|foldername>
        This command sets your current folder to <folder#>.

  @mail/folder <folder#> = <foldername>
        This command gives <folder#> a name.

  @mail/file <msg-list>=<folder#>
        This command moves all messages in msg-list from the current
        folder to a new folder, <folder#>.

& MAIL-OTHER
MAIL-OTHER

  @mail/clear [<msg-list | all>]
  @mail/unclear [<msg-list> | all>]
        These commands mark mail in the current folder as cleared or
        uncleared. Mail marked for clearing is deleted when you
        disconnect, or if you use @mail/purge. If no msg-list is
        specified, all mail in your current folder is cleared. If "all"
        is given instead of a msg-list, all mail in *all* folders is
        cleared/uncleared.

  @mail/purge
        Actually deletes all messages marked for clearing with
        @mail/clear. This is done automatically when you log out.

  @mail/tag [<msg-list | all>]
  @mail/untag [<msg-list> | all>]
        These commands tag or untag mail in the current folder.
        Tagged mail can be later acted on en masse by using "tagged" as
        the msg-list for other commands (which does *not* untag them
        afterward). If no msg-list is specified, all messages in the
        current folder are tagged/untagged. If "all" is given as the
        msg-list, all mail in *all* folders is tagged/untagged.
        (Ex: To clear all mail from Temperance and Sloth,
        @mail/tag *temperance, @mail/tag *sloth, @mail/clear tagged,
        @mail/untag all).

& MAIL-OTHER2
MAIL-OTHER (continued)

  @mail/safe [<msg-list> | all>]
        This command marks a message as being safe from mail expiration. It
        should be used sparingly and only for very important messages.

& MAIL-READING
MAIL-READING

  @mail <msg #>
  @mail/read <msg-list>
        This displays messages which match the msg# or msg-list from
        your current folder.

  @mail
  @mail <msg-list, but not a single msg #>
        This gives a brief list of all mail in the current folder,
        with sender name, a list of receiving players, subject, and
        message status.
  @mail/list [<msg-list>]
        This gives the same list, but with time sent instead of subject.
        The status field is a set of characters (ex: NC-UF+) which mean:
                N = New (unread) message
                C = Cleared message
                U = Urgent message
                F = Forwarded message
                + = Tagged message
        The opposites of these (read messages, etc.) are indicated with a
        '-' in the status field in that position.

& MAIL-REVIEWING
MAIL-REVIEWING

  @mail/review <player>
        Reviews the messages you have sent to <player>.

  @mail/review <player>=<msglist>
        Reads the messages you have sent to <player>.

  @mail/retract <player>=<msglist>
        Retracts (deletes) unread messages you have sent to <player>.

& MAIL-SENDING
MAIL-SENDING

  @mail[/switch] <player-list> = <subject>
        This begins a message to all players in <player-list>.
        -<text> adds text to the message in progress, for example
            -This is a test
        would add the text 'This is a test' to the end of your @mail
        message, likewise, ~<text> prepends the text.

  @mail/send
        This sends the message that is currently in progress.
        -- is the equivalent of @mail/send. @mail/urgent sends
        the message as urgent, and should not be used often.

  @mail/cc <player-list>
        This replaces the current player list with a new one for carbon
        copying. It does _not_ add onto the existing list.

{ 'help mail-sending2' for more }

& MAIL-SENDING2
MAIL-SENDING (continued)

  @mail/proof
        This shows you the message that is currently in progress, as
        it would be read by whomever received it.

  @mail/edit <old text> = <new text>
        Like @edit, but edits the message in process.

  @mail/abort
        This aborts the message currently in progress, allowing you
        to start a new one.

  @mail/fwd <msg> = <player-list>
        This sends a copy of <msg> to all the players in <player-list>.
        The copy will appear to have been sent by you (not the original
        sender), and its status will be "Forwarded". Note that this
        places the message to be forwarded into your mail buffer, where
        you can edit it with @mail/edit, add text with '-', or prepend
        text with '~'. You have to use '--' or @mail/send to send the
        message.

  @mail/quick <player-list>/<subject> = <message>
        Sends <message> to the list of players.

{ 'help mail-sending3' for more }

& MAIL-SENDING3
MAIL-SENDING (continued)

  @mail/reply[/quote] <message>
        This starts a working message to the person who sent you <msg>.

  @mail/replyall[/quote]
        This starts a working message to the person who sent you <msg>
        and to every other recipient of <message>.

  In both cases, because this is a reply, the subject line will be:

        'Re: <subject line from original message>'

  Also, in both cases, if /quote is specified, the original message
  will be quoted into the working message with a header and footer much
  like the following:

        On Thu Apr 27 21:33:04 2000, Gordon wrote:

        <quoted message from original message>

        ********** End of included message from Gordon

  You can add additional text above or below the quoted material with
  the postpend ('-') and prepend ('~') @mail commands. Like, normal
  outgoing @mail, the reply is finished and sent with '--' on a line
  by itself

& MAILFROM()
MAILFROM()

  FUNCTION: mailfrom(<msg #>)

  Returns the dbref # of the player who sent you <msg #>. Wizards may
  specify mailfrom(<player>,<msg #>).

  Related Topics:

& MAP()
MAP()

  FUNCTION: map([<obj>/]<attr>,<list>[,<input delim>[,<output delim>]])

  This function is nearly identical to an iter() operating on u() function.
  Each member of <list> is passed to the result of fetching <attr> as %0, and
  the results are used to form a new list.

  In addition to any single character, <output delim> can also be the null-
  delimiter, @@, or a newline, %r.  By default, input and output delimiters
  are both space.

  Examples:
    > &ADD_ONE object=add(%0,1)
    > say map(object/add_one,1 2 3 4 5)
    You say "2 3 4 5 6"

& MATCH()
MATCH()

  FUNCTION: match(<string>, <pattern>[, <delim>])

  This function matches <pattern> against each word of <string>, returning
  the number of the first word that matches.  If no words match then 0 is
  returned.  The case of the characters being matched is not significant.

  The pattern may contain the wildcards '*' and '?'.  '?' matches any one
  character, while '*' matches any number of characters, including none.
  So 's?x' would match 'sex' or 'six', but not to 'socx', but 's*x' would
  match any of them.

  <delim> may be used specified to specify a delimiter other than a space.

  Examples:
    > say match(This is a test, test)
    You say "4"
    > say match(This is a test, is)
    You say "2"
    > say match(This is a test, *is*)
    You say "1"
    > say match(This is a test, *not*)
    You say "0"
    > say match(This is a test, is a)

& MATCHALL()
MATCHALL()

  FUNCTION: matchall(<string>,<pattern>[,<delim>])

  This function works identically to the match() function, save that it
  returns all matches, not just the first: It returns the index numbers of
  all words in the list <string> which match <pattern>.

  Examples:
    > say matchall(This is a test of a test,test)
    You say "4 7"
    > say matchall(This is testing a test,tes*)
    You say "3 5"

  The MATRIX flag is used to denote an object who is in the Matrix or
  Digital Web. Rooms will list contents as |Icons| and will only list
  players and objects also set MATRIX. MATRIXDESC can be set on a
  player or object as the description of their icon.

& MAX()
MAX()

  FUNCTION: max(<number1>,<number2>[,<numberN]...)

  Returns the largest integer from among its arguments.
  Up to 30 arguments may be specified.
  <numberN> may be a floating point number, and a floating point result
  is returned.

  Examples:
    > say max(2,4)
    You say "4"
    > say max(-100,50,0,25)
    You say "50"

& ME
ME

  The word 'me' refers to yourself. Some things to do when starting out:
  1) give yourself a description with
     '@describe me = <description>', then look at yourself with 'look me'.
  2) set your gender, if you wish it known, with
     '@set me=male' or '@set me=female'  (or '@set me=neuter' to be an 'it').

& MEDIUM
MEDIUM

  The MEDIUM flag denotes a player who is a medium. With this flag set
  they can hear what is said by those set SHROUD but not see them. They
  can see those who are visible normally only.

& MEMBER()
MEMBER()

  FUNCTION: member(<list>, <word>[, <delim>])

  Member takes a list and a word, and returns the position of that word
  within the list.  If the word does not occur in the list, then 0 is
  returned.  Unlike match(), member() does not check for wildcarding,
  and the cases of <list> and <word> are significant.  A word is defined as
  a string which has no interior spaces.  So 'hello' would be one word,
  while 'hello there' would be two.

  <delim> may be used to specify a delimiter other than a space.

  Example:
    > say member(This is a member test, member)
    You say "4"
    > say member(This is a member test, Member)
    You say "0"
    > say member(This is a member test, *e*)
    You say "0"
    > say member(This is a member test, is a)
    You say "0"

& MERGE()
MERGE()

  FUNCTION: merge(<string1>,<string2>,<character>)

  This function merges <string1> and <string2>, depending on <character>.
  If a character in <string1> is the same as <character>, it is replaced
  by the character in the corresponding position in <string2>.  The two
  strings must be of the same length.

  Spaces need to be treated specially. A null character is considered to
  equal a space, for <character>.

  Examples:
    > say merge(AB--EF,abcdef,-)
    You say, "ABcdEF"
    > say merge(AB[space(2)]EF,abcdef,)
    You say, "ABcdEF"

  Related Topics: splice().

& MID()
MID()

  FUNCTION: mid(<string>, <first>, <length>)

  Mid returns a segment of the string, the <length> characters to the right
  of the <first> character.  Note that the first character in a string is
  numbered zero, and not one.

  If you are looking for left(), then look at strtrunc() as an equivalent.

  Related Topics: right(), strtrunc().

& MIN()
MIN()

  FUNCTION: min(<number1>,<number2>[,<numberN]...)

  Returns the smallest integer from among its arguments.
  Up to 30 arguments may be specified.
  <numberN> may be a floating point number, and a floating point result
  is returned.

  Examples:
    > say min(2,4)
    You say "2"
    > say min(-100,50,0,25)
    You say "-10"

  Related Topics: max()

& MIX()
MIX()

  FUNCTION: mix([<object>/]<attribute>,<list 1>,<list 2>[,<list N>][,<delim>])
  
  This function is similar to map(), except it takes the arguments in the 
  lists and passes them into the attribute as %0 (for list1), %1 (for list2),
  up to %9 (for list10).  <delim> is used as the delimiter to separate items
  in each of the lists.  If the number of lists is 2, the delimiter may be
  optional, otherwise you are forced to provide a delimiter.  If no delimiter
  is specified, it defaults to a space but only for the above condition.
  The lists do NOT have to have the same number of elements.
  
  Examples:
    > &do_math me=[add(%0,%1)]
    > &do_moremath me=[add(%0,%1,%2,%3,%4,%5,%6,%7,%8,%9)]
    > say mix(do_math,1 2 3 4 5,2 4 6 8 10)
    You say "3 6 9 12 15"
    > say mix(do_math,1@2@3@4@5,2@4@6@8@10,@)
    You say "3@6@9@12@15"
    > say mix(do_math,1 2 3 4 5,7 9)
    You say "8 11 3 4 5"
    > say mix(do_moremath,1,2,3,4,5,6,7 8,9 10 11 12,)
    You say "37 18 11 12"

& MOD()
MOD()

  FUNCTION: mod(<integer1>,<integer2>)

  Returns the integer remainder from dividing <integer1> by <integer2>.

  However, integer division for the case where either <integer1> or
  <integer2> is negative is defined in a specific way -- by choosing
  the largest integer that is less than or equal to the algebraic
  quotient. If <integer1> and <integer2> are the same sign, then
  mod() and remainder() are equivalent.

  For example, division of -9 by 5 would give -2 by this definition
  instead of -1. idiv() would return -1. floordiv() would return -2,
  and so, the mod() function properly goes with the floordiv()
  function:

    floordiv(x,y)*y + mod(x,y) ==> x

  For positive y, mod(x,y) always returns a positive number less than
  y. For negative y, mod(x,y) always returns a negative number greater
  than y.

  mod() is the more 'mathy' definition of a modulus as defined by the
  following:

    x mod y  is defined as x - y*floor(x/y) where x,y, every operation
    is over real numbers.

  Example:
    > say mod(-9,5)
    You say "1"
    > say mod(-9,-5)
    You say "-4"
    > say mod(17,3)
    You say "2"
    > say mod(18,3)
    You say "0"

& MONEY
MONEY

  You need money to build within the game, to run programmed objects or use
  certain other commands, or to buy things from vendors set up by other
  players.  You can get money via one or more of these methods:
    1.  You receive a daily allowance for each day you connect.
    2.  You have a chance of finding money as you wander around areas that
        other people have built.
    3.  Some MUXes may implement a place where you can sell valuable objects
        for money.

  Related Topics: @list costs, COSTS.

& MONEY()
MONEY()

  FUNCTION: money(<object>)

  Returns an integer equal to the amount of money <object> has (if it is a
  player) or is worth (otherwise).

  Example:
    > score
    You have 1052 clams.
    > say money(me)
    You say "1052"
    > exam sac test
    Sac Test(#287V)

MONIKER()

  Function: moniker([<object>])

  This function returns the value of an object's MONIKER attribute.  The
  the accented/colorized name must match the normal name or the normal NAME
  attribute is returned instead of the decorated one.

  Related Topics: @name, ansi(), @moniker, chr(), ord(), NOACCENT,

& MONITOR
MONITOR

  FLAG: MONITOR(M)  ()

  Objects:
  When set, anytime the object hears something from someone who passes the
  object's use lock, the object's attributes are scanned for attributes
  of the form '^<pattern>:<commandlist>'.  If the message matches the
  wildcarded <pattern>, then <commandlist> is executed, substituting %0 for
  the text that matched the first wildcard, %1 for the second, and so on.
  All matching attributes are executed, not just the first.
  Parents of MONITOR objects are never checked for ^-patterns.

  Players:
  When set on a player, this flag notifies that player whenever someone
  connects or disconnects from the MUX. It is valid only for players, and
  must be set by a wizard.

  FUNCTION: motd()

  motd() returns the current MOTD as set using @motd.

& MOVE
MOVE

  COMMAND: move[/<switch>] <direction>
           move[/<switch>] home
           <direction>
           home

  Moves you in the specified direction, assuming that the direction is not
  locked against you.  'move home' is a special command that returns you to
  your home. The word 'move' may be omitted.

  The following switch is recognized:

     /quiet   - Don't perform the @osucc/@asucc/@odrop/@adrop or @ofail/@afail
                attributes on the exit being used.  This switch only works if
                you control the exit.

  'goto' is the same as 'move'.

  Related Topics: enter, home, leave.

& MOVING
MOVING

  A number of things happen when you leave one location and enter another
  (assuming you pass the lock on the exit or have permission to enter the
  object or to teleport to the location).  The following list describes the
  actions that MUX takes when an object moves from one place to another.
  Note that if an indicated attribute is not set, no message is displayed
  (or no action is performed).

  - If you are using an exit (as opposed to teleporting, entering an object,
    or going home), You receive the SUCC message for the exit, others in the
    old location receive the exit's OSUCC message, and the exit runs its
    ASUCC action list.
  - If you are teleporting or being teleported, others in the old location
    receive your OXTPORT attribute.
  - If you are a player or have your LISTEN attribute set to something,
    and if the old location is not dark and you are not dark, you receive the
    LEAVE message for the old location, others in the old location receive
    the OLEAVE message, and the old location runs its ALEAVE action list.
    Others in the new location receive the OXENTER message from the old
    location, and others in the old location receive the message '<yourname>
    has left.'

{ 'help moving2' for more }

& moving2
MOVING (continued)

  - You are moved to the new location.  If you are entering an object,
    teleporting, or going home, all KEY objects are stripped from you.
  - If the new location is a room, you receive the room's DESC, others in the
    room receive the ODESC, and the room runs its ADESC.  If you pass the
    room's lock do the same with SUCC, OSUCC, and ASUCC, otherwise use FAIL,
    OFAIL, and AFAIL.
  - If the new location is a player or an object, you receive the location's
    IDESC (or DESC if the IDESC is not set).  In either event, others in the
    same location see the ODESC message and the location runs its ADESC
    action list.
  - You are shown the contents and visible exits if the location is not DARK.
  - If you used an exit, then you receive the DROP message for the exit,
    others in the new room receive the exit's ODROP message, and the exit
    runs its ADROP action list.
  - If you are teleporting or being teleported, you receive your TPORT
    attribute, others in your new location receive your OTPORT attribute,
    and your ATPORT attribute is run.
  - You receive your MOVE attribute, others in your new location receive
    your OMOVE attribute, and your AMOVE attribute is run.

{ 'help moving3' for more }

& moving3
MOVING (continued)

  - If you are a player, or have your LISTEN attribute set to something,
    and if the old location is not dark and you are not dark, you receive the
    ENTER message for the new room, others in the new room receive the OENTER
    message, and the new room runs its AENTER action list. Others in the room
    you just left receive the new room's OXLEAVE message, and others in the
    old location receive the message '<yourname> has arrived.'
  - If the old location is a STICKY room and has its drop-to set, see if
    objects in that room should be sent to the drop-to location.  If so,
    do it.
  - If you are a player, you have a chance of finding some money.

& MTIME()
MTIME()

  FUNCTION: mtime(<object>)

  Returns <object>'s last modification time as a time() string. Invoking
  the function without an argument is equal to mtime(me)

  An object's mtime will be affected by any changes to the attributes,
  such as @desc, @va, or & attributes. Is is also affected by renaming
  the object.

  Example:
    > think mtime(me)
    Mon Oct 08 18:33:03 2001

& MUDNAME()
MUDNAME()

  FUNCTION: mudname()

  Returns the name of the MUD.  This is usually (but not necessarily) the name
  that appears in the various mud lists, and is the name that the mud is
  listed under in reports from RWHO servers (that is, if the mud sends its
  WHO information to an RWHO server).

  Example:
    > say mudname()
    You say "TestMUX"

& MUL()
MUL()

  FUNCTION: mul(<number1>[,<numberN>]...)

    > say mul(3,5)
    You say "15"
    > say mul(3,5,-2)
    You say "-30"

& MUNGE()
MUNGE()

  FUNCTION: munge([<object>/]<attribute>,<list 1>,<list 2>[,<delimiter>])

  This function takes two lists of equal length. It passes the entirety of
  <list 1> to the user-defined function as %0 and the delimiter as %1.
  Then, this resulting list is matched with elements in <list 2>, and the
  rearranged <list 2> is returned. This is useful for doing things like
  sorting a list, and then returning the corresponding elements in the other
  list. If a resulting element from the user-defined function doesn't match
  an element in the original <list 1>, a corresponding element from <list 2>
  does not appear in the final result.

  For example: Consider attribute PLACES, which contains "Fort Benden Ista",
  and another attribute DBREFS contains the dbrefs of the main JUMP_OK
  location of these areas, "#20 #9000 #5000".  We want to return a list of
  dbrefs, corresponding to the names of the places sorted alphabetically. The
  places sorted this way would be "Benden Fort Ista", so we want the final
  list to be "#9000 #20 #5000". The functions, using munge(), are simple:

  Example:
    > &sort_alpha me=[sort(%0)]
    > say [munge(sort_alpha,v(places),v(dbrefs))]
    You say, "#9000 #20 #5000"

MYOPIC

  FLAG: MYOPIC(m)  ()

  If you are set MYOPIC, then you are treated as if you did not own anything
  when you use the LOOK command or when you automatically look at a location
  when entering it.  Other commands (such as EXAMINE) are not affected.

NEARBY()

  FUNCTION: nearby(obj1,obj2)

  Tests if obj1 is near obj2 (if it is in the same location, in obj2's
  inventory, or is obj2's location).  You must control either obj1 or obj2, or
  be near either one of them, if both of these tests fail then 0 is returned.
  This function returns 1 if the two objects are nearby and 0 if not.

  Related Topics:

& NEQ()
NEQ()

  FUNCTION: neq(<integer1>,<integer2>)

  Takes two integers, and returns 1 if they are not equal and 0 if they are
  equal.  Warning: passing anything but integers will produce unexpected
  results, as non-numeric strings usually are treated as numeric 0.

  Examples:
    > say neq(1,-1)
    You say "1"
    > say neq(5,5)
    You say "0"
    > say neq(foo, bar)

  FUNCTION: next(<thing>)

  If thing is an exit in a room, then next will return the next
  nondark exit in the list of exits for that room.  If thing is an
  object, then next will return the next object in the inventory list
  that the object is in.  Otherwise, it returns a '#-1' string.

& NOACCENTS
NOACCENTS

  FLAG: NOACCENTS(~)

  When set on a player, it will disable a player from seeing the accent marks
  above certain letters. The default is for the accent marks to be shown.

  This flag has no associated letter.

  Related Topics: stripaccents(), chr(), ord().

& NOBLEED
NOBLEED

  FLAG: NOBLEED(-)  ()

  When set on a player, it will append an ANSI white character to
  the normal ANSI 'normal' character, so it will fix ANSI color 'bleed' on
  most terminals. (Bleed occurs when a color extends into text it was not
  meant to.) Do not set this flag unless you have to, it tends to slow down
  the text display for the MUX.

& NOT()
NOT()

  FUNCTION: not(<boolean>)

  Takes a BOOLEAN value, and returns its inverse.  So, if the input is
  equivalent to TRUE it returns a FALSE(0), and if the input is equivalent to
  FALSE, it returns a TRUE(1).

  Related Topics: BOOLEAN VALUES, and(), or(), t(), xor().

& NO_COMMAND
NO_COMMAND

  FLAG: NO_COMMAND(n)  ()

  The NO_COMMAND flag disables the checking of $-commands
  on an object.

  Most MUXes will be configured to automatically set this flag on rooms
  and players. The server runs faster when fewer objects are checked for
  $-commands; thus, any object which does not have $-commands on it should
  be set NO_COMMAND.

& OBF
OBF

  The OBF Flag is used to denote someone using a form of invisibility,
  most commonly the vampiric discipline of Obfuscate. They must also have
  an attribute set on them, OBF_LEVEL, which denotes the level of
  invisibility they posses. When this attribute is present and the flag is
  set on them they do not show up in the contents list of rooms. If a
  player moves through an exit and has OBF_LEVEL of 1 then they will no
  longer be invisible and will trigger the exit message. OBF_LEVEL of 2 or
  higher will no longer do this. At OBF_LEVEL is 3 or higher they can set
  their true desc in the attribute OBFDESC so that it will only be seen by
  those with the ability to see through their disguise.

  or be near <object>.

  Related Topics: aposs(), poss(), subj(), SUBSTITUTIONS.

& OBJECT STACK
OBJECT STACK

  NOTE: The object stack is completely different from the command stack
  ('help stack').

  A stack is a LIFO structure, meaning that the last, most recent thing you
  place into it is the first thing you get out of it. You 'push' an item
  onto the stack, and you can 'pop' it off, or merely take a 'peek' at it.
  If you pushed the word 'foo', and then the word 'bar', and popped
  something off the stack, you would first pop 'bar', then 'foo'. You pop
  or peek in the reverse order that you pushed.

  The object stack can hold any kind of information. In this manner they are
  similar to r-registers, but are more flexible. There is a high limit to the
  number of stack entries you can have (usually 100), and stack entries are
  preserved until you pop them off or empty the stack.

& OBJECT STACK2
OBJECT STACK (continued)

  Example:

  > say [push(world!)][push(Hello)]We'll print these...
  We'll print these...
  > say [pop()] [pop()]
  Hello world!

  empty() is used to clear the stack, items() shows the number of entries in
  the stack.

& OBJECT TYPES
OBJECT TYPES

  There are 4 types of objects: things, players, exits, and rooms.  The first
  letter following an object's ID number indicates the type: P(layer), E(xit),
  R(oom), otherwise, thing.  Things are inanimate objects that can be carried.
  Players are animate objects that can move and carry.  Exits are the means by
  which objects move from room to room.  Rooms are locations that contain
  objects and linked exits.

OBJEVAL()

  FUNCTION: objeval(<object>,<expression>)

  Allows you to evaluate <expression> from the viewpoint of <object>.
  You must be a wizard or own <object> to use this function. If <object>
  does not exist or you don't meet the criterion, the function evaluates
  with your privileges. No one may use this function on #1.

  This function is useful for securing objects which need to evaluate
  attributes on things owned by others.

& ORFLAGS()
ORFLAGS()

  FUNCTION: orflags(<object>,<list of flags>)

  This function returns 1 if <object> has at least one of the flags in
  a specified list, and 0 if it does not. The list is specified with a
  single letter standing for each flag, like the output of the FLAGS()
  function. A '!' preceding a flag letter means "not flag".

  Thus, ORFLAGS(me,Wr) would return 1 if I were set WIZARD or ROYALTY.
  ORFLAGS(me,D!c) would return 1 if I were DARK or not CONNECTED.

  If a letter does not correspond to any flag, <object> doesn't have
  it, so it is simply ignored. There can be an arbitrary number of
  flags. Do not put spaces between flag letters.

& PACK()
PACK()

  FUNCTION: pack(<number>[,<radix>])

  Returns the equivalent of the given number using the specified base.
  The default radix is 64. Bases greater than 10 will be more compact
  than the original number. Bases less than 10 will be more expanded.

  The inverse function of pack is unpack. pack and unpack are designed
  to support the base-36 radix conversion used in Myrddin's popular

           page[/noeval] [<prefix>]<message>
           page <players>=
           page

  This command sends <message> to <players>.  The second and third form sends
  the given message to the same <players> given on the previous page command.
  The second form is useful when the message itself contains an equal sign.

  The fourth form indicates that you are paging sans-message.  The format is
  somewhat more appealing than an empty message.

  The last form reports to you the list of players you paged last time.

  <Players> is one or more player names or aliases delimited by any
  combination of spaces or commas.  Double-quotes can be used around any name
  containing spaces.  A player's name may also be any unique prefix of players
  who are currently on the WHO list.  Any duplicate players from your list are
  removed.

  If your Idle attribute is set to something, then it is sent to anyone who
  successfully pages you after you have become idle by the period set by your
  @idletimeout.  This is useful for when you are away from your terminal for
  a short while.

  Also, you can selectively disable pages from certain players with the
  '@lock/page' command (players must pass the lock in order to page you). If
  someone cannot page you, they will be sent a message including your Reject
  attribute if they try.  If someone pages you while you are not connected,
  they are sent a message including your Away attribute.

  You can also page many players at one time, where all the players you page
  will see the message.

  Example:
    > p Foo, Bar, "Long John Silver"= Hi
    You paged (Foo, Bar, Long John Silver) with 'Hi'.
    To (Foo, Bar), Widget pages: Hi

  You only need to type the player-list once, then the next time you page that
  player or set of players, you can abbreviate it with:

    "p :waves."  or,
    "p I'm back."

  This will work until you page another player or list of players.

& PARENT OBJECTS
PARENT OBJECTS

  TOPIC: PARENT OBJECTS

  Parent objects provide a way for several objects to inherit common
  attributes, exits, and $-commands from a single object, so that changing
  the parent object affects all of its children.  When searching for
  attributes or exits, first the object itself is checked, then the parent
  is checked only if the object does not have what was searched for.

  Any attribute the parent object has will be passed down to its children,
  if they don't already have one. For instance, if the child object has no
  description, it will inherit the description of its parent.

  Any exits the parent object has will show up in the exit list of the
  child, and may be used as normal exits.

  The parent is searched for $-commands as well as the child, and only
  attributes that are unique to the parent are checked, so that conflicting
  attribute names are skipped.  If both have an attribute named "cmd1",
  only the child's "cmd1" attributes is checked for a $-command.

{ 'help parent2' for more }

& PARENT ROOMS
PARENT ROOMS

  Parent rooms are a subset of zones. If a room is used as a zone object,
  it is a parent room (PR). PRs are like local "master" rooms. Exits in
  the PR are global to that zone, and $commands on objects in the PR are
  global to that zone. Parent rooms are only defined if globals are used.
  Parent rooms should only be used for very large zones which have a lot
  of global exits. Otherwise, a ZMO thing should be used, because command
  evaluation on a parent room is slower than command evaluation on a ZMO.
  Large numbers of parent rooms may slow down the game significantly.

& PARENT()
PARENT()

  FUNCTION: parent(<obj>)

  Returns the parent of <obj>.  Returns #-1 if <obj> cannot be found or

& PARENT2
PARENT OBJECTS (continued)

  A parent object may itself have a parent, up to a configurable limit
  (usually 10 levels).  The parent need not be the same type as its children,
  and flags and locks are not inherited from parent objects.  You may not
  create parent loops.

  Related Topics: @parent, parent().

& PARENT_OK
PARENT_OK

  FLAG: PARENT_OK(Y)  ()

  If an object is set PARENT_OK, then any other object that passes the object's
  ParentLock may make this object a parent of any object that it controls.
  Caution: allowing others to use your objects as parents lets them read the
  attributes on the object (as well as any parents of the object).

& PARSE()
PARSE()

  FUNCTION: parse(<list>,<eval>[,<input delim>[,<output delim>]])

  This function takes each element of <list>, evaluates <eval> after
  substituting it for ##, and constructs a list of the results. Input
  and output delimiters are both space by default.

  Examples:
    > say parse(1 2 3 4 5,add(##,1))
    You say "2 3 4 5 6"
    > say parse(This|is|a|string|length|test,strlen(##),|)

& PEEK()
PEEK()

  FUNCTION: peek([<object>], [<position>])

  peek() returns an item from the caller's stack without removing it from
  the stack. If <position> is specified, it returns the item from that
  position in the stack (items in the stack are numbered with 0 being the most
  recently push()ed item), otherwise, it returns position 0. If <object> is
  specified and you control it, then it returns an item from <object>'s
  stack.

& PEERING
PEERING

  The PEERING flag is used to denote an object which is looking into
  another realm but is not visible there. It requires the attribute
  PEERING_REALM be set with a value of the realm being watched. The
  value MUST be in all uppercase letters.

& PEMIT()

  FUNCTION: pickrand(<word1> <word2> <...<wordN>[,<delimiter>])

  This function picks a random element from a list.  It's faster than
  first(shuffle(foo)) or extract(foo,rand(words(foo)),1).  <delimiter> is an
  optional one-character output delimiter.

  Example:
    > say pickrand(foo bar baz)
    You say "bar"

& PIPING
PIPING

  Command piping in MUX is similar to piping in a UNIX shell. You string two
  or more commands together using the ;| symbol, much as you would using a
  semicolon. The output from the previous command in a pipe is accessible
  using the %| substitution. This output contains the raw ASCII codes that
  would normally be directly output to your terminal. You may use the
  translate() function to either convert the raw characters in the output to
  MUX substitutions, or strip them out altogether. Like the semicolon, the ;|
  symbol in MUX is taken literally if you type it on the terminal. Currently
  you may only pipe 20 commands in a row.

  Examples:
  > &MAILDESC me=$+maildesc *=*:look %0 ;| @mail/quick
                  %1/Description=[translate(%|,1)]
  > &SAYDESC me=$+saydesc *:look %0 ;| say %r%|
  > +saydesc me
  You say "

& PLAYMEM()
PLAYMEM()

  FUNCTION: playmem(<player>)

  Note that this is the total number of bytes that the player uses,
  including all objects that they own. You must be a Wizard, or have
  the search power to use this function on another player.

& PMATCH()
PMATCH()

  FUNCTION: pmatch(<string>)

  Given the partial name of a player, it returns that player's dbref
  number. This partial name completion works identically to the partial
  name completion of the "page" command - i.e. it first attempts to match
  the normal names of all players (connected or not), and if that fails,
  it tries to match the partial names of connected players. If no player
  is matched, it returns "#-1". If multiple matches are found, it returns
  the first match, in order of connection time.

  Pmatch() will also accept *<player> or #<db#>. If given a non-player
  dbref #, pmatch() will return #-1.

  FUNCTION: pop([<object>[,<position>]])

  pop() returns an item from the caller's stack and removes it from
  the stack. If <position> is specified, it returns the item from that
  position in the stack (items in the stack are numbered with 0 being the most
  recently push()ed item) and removes it, otherwise, it returns position 0.
  If <object> is specified and you control it, then it returns an item from
  <object>'s stack.

  FUNCTION: ports(<player name>)

  This function returns the list of descriptors ("ports") that a player,
  specified by full player name, or by dbref, is connected to. Wizards
  can use this function on anyone, but mortals can only use it on
  themselves.

  If the <player> is not connected, an empty list is returned. Otherwise,
  a list of ports is returned in order of most recent connection to least
  recent connection. These ports correspond to those given by the SESSION
  command.

  An object is made into a puppet by doing '@set <object>=puppet', once an

  All objects created by a puppet are owned by its master, when puppets spend
  or earn money, they use their master's money supply.  In order to prevent
  puppets from screwing up puzzles, objects may have the KEY flag set, this
  will prevent puppets from picking the object up. A puppet may be commanded
  by its master by '@force <object>=command', or by the shorthand version,
  '#<number of puppet> command'.  The puppet flag is handy for debugging, as
  it allows you to see the result messages your object generates.

& REGEXP AMBIGUITY
REGEXP AMBIGUITY

  TOPIC: Regular Expression Ambiguity

          If a regular expression could match two different parts of
          the input string, it will match the one which begins
          earliest.  If both begin in the same place but match
          different lengths, or match the same length in different
          ways, life gets messier, as follows.

          In general, the possibilities in a list of branches are
          considered in left-to-right order, the possibilities for
          `*', `+', and `?' are considered longest-first, nested
          constructs are considered from the outermost in, and
          concatenated constructs are considered leftmost-first.  The
          match that will be chosen is the one that uses the earliest
          possibility in the first choice that has to be made.  If
          there is more than one choice, the next will be made in the
          same manner (earliest possibility) subject to the decision
          on the first choice.  And so forth.

{ 'help regexp ambiguity2' for more }

& REGEXP AMBIGUITY2
REGEXP AMBIGUITY (continued)

          For example, `(ab|a)b*c' could match `abc' in one of two
          ways.  The first choice is between `ab' and `a'; since `ab'
          is earlier, and does lead to a successful overall match, it
          is chosen.  Since the `b' is already spoken for, the `b*'
          must match its last possibility-the empty string-since it
          must respect the earlier choice.

          In the particular case where no `|'s are present and there
          is only one `*', `+', or `?', the net effect is that the
          longest possible match will be chosen.  So `ab*', presented
          with `xabbbby', will match `abbbb'.  Note that if `ab*' is
          tried against `xabyabbbz', it will match `ab' just after
          `x', due to the begins-earliest rule.  (In effect, the
          decision on where to start the match is the first choice to
          be made, hence subsequent choices must respect it even if
          this leads them to less-preferred alternatives.)

& REGEXP SYNTAX
REGEXP SYNTAX

  TOPIC: Regular Expression Syntax

  The following explanation is taken from Henry Spencer's regexp(3)
  package, the regular expression library used in TinyMUX up to version
  2.2. After that, the PCRE package is used, which has many more features.
  See a book that covers Perl's regular expressions for details.

          A regular expression is zero or more branches, separated by
          `|'.  It matches anything that matches one of the branches.

          A branch is zero or more pieces, concatenated.  It matches a
          match for the first, followed by a match for the second,
          etc.

          A piece is an atom possibly followed by `*', `+', or `?'.
          An atom followed by `*' matches a sequence of 0 or more
          matches of the atom.  An atom followed by `+' matches a
          sequence of 1 or more matches of the atom.  An atom followed
          by `?' matches a match of the atom, or the null string.

{ 'help regexp syntax2' for more }

& REGEXP SYNTAX2
REGEXP SYNTAX (continued)

          An atom is a regular expression in parentheses (matching a
          match for the regular expression), a range (see below), `.'
          (matching any single character), `^' (matching the null
          string at the beginning of the input string), `$' (matching
          the null string at the end of the input string), a `\'
          followed by a single character (matching that character), or
          a single character with no other significance (matching that
          character).

          A range is a sequence of characters enclosed in `[]'.  It
          normally matches any single character from the sequence.  If
          the sequence begins with `^', it matches any single
          character not from the rest of the sequence.  If two
          characters in the sequence are separated by `-', this is
          shorthand for the full list of ASCII characters between them
          (e.g. `[0-9]' matches any decimal digit).  To include a
          literal `]' in the sequence, make it the first character
          (following a possible `^').  To include a literal `-', make
          it the first or last character.

& REGEXPS
REGEXPS

  TOPIC: Regular Expressions

  The majority of matching in MUX is done with wildcard ("globbing")
  patterns. There is a second type of matching, using regular expressions,
  that is available in certain circumstances.

  For attributes that are $-commands or ^-listen-patterns, setting that
  attribute "regexp" (with '@set <object>/<attribute>=regexp') causes
  patterns to be matched using regular expressions rather than globbing.

  In a regular expression match, the substring of the string which matched
  the regexp pattern is %0; %1 through %9 are the substrings of the string
  which matched parenthesized expressions within the regexp pattern.

{ 'help regexps2' for more }

& REGEXPS2
REGEXPS (continued)

  Regular expressions are extremely useful when you want to enforce
  a data type. For example, if you have a command where you want a
  player to enter a string and a number ('+setnum <player>=<number>',
  for example), you might do it like this:

  &DO_NUM Command Object=$+setnum (.+)=([0-9]*): @va me=Data: %1 = %2
  @set Command Object/DO_NUM = regexp

  Then, '+setnum cookies=30' would set VA to "Data: cookies = 30".
  This eliminates your having to check to see if the player entered
  a number, since the regular expression matches only numbers.
  Furthermore, the '+' guarantees that there needs to be at least
  one character there, so a player can't enter '+setnum cookies='
  or '+setnum =10' or similarly malformed input.

  Also note that regexps are case-sensitive, but wildcard globbing is not.
  Some regular expression functions offer case-insensitive versions, some
  regexp can be made case-insensitive by putting (?i) at the start.
  Setting the CASE attribute flag is another way of selecting
  case-insensitivity.

& REGMATCH()
REGMATCH()
REGMATCHI()

  FUNCTION: regmatch(<string>,<regexp>[,<register list>])

  This function matches the regular expression <regexp> against the
  entirety of <string>, returning 1 if it matches and 0 if it does not.
  Normally, the regular expression is case sensitive. The regmatchi()
  version is not.

  If <register list> is specified, there is a side-effect: any
  parenthesized substrings within the regular expression will be set
  into the specified local registers, in the order they were specified
  in the list. <register list> can be a list of one through nine
  numbers or A through Z.  If the specified register is -1, the
  substring is not copied into a register.

  For example, if <string> is 'cookies=30', and <regexp> is '(.+)=([0-9]*)'
  (parsed; note that escaping may be necessary), then the 0th substring
  matched is 'cookies=30', the 1st substring is 'cookies', and the 2nd
  substring is '30'. If <register list> is '0 3 5', then %q0 will become
  "cookies=30", %q3 will become "cookies", and %q5 will become "30".
  If <register list> was '0 -1 5', then the "cookies" substring would
  simply be discarded.

  See 'help regexp syntax' for an explanation of regular expressions.

& REGRAB()
REGRAB()

  FUNCTION: regrab(<list>, <regexp>[, <separator>])
            regrabi(<list>, <regexp>[, <separator>])
            regraball(<list>, <regexp>[, <separator>])
            regraballi(<list>, <regexp>[, <separator>])

  These functions act like grab() and graball(), respectively, except
  instead of matching with a wildcard pattern, they use a regular
  expression.  regrab() returns the first element of the list that
  matches the regexp, and regraball() returns all the elements that
  match.  They are case-sensitive. The versions ending in 'i' are
  case-insensitive.

& REMAINDER()
REMAINDER()

  FUNCTION: remainder(<integer1>,<integer2>)

  Returns the integer remainder from dividing <integer1> by <integer2>.

  However, integer division for the case where either <integer1> or
  <integer2> is negative is defined in a specific way -- by choosing
  the smallest integer that is greater than or equal to the algebraic
  quotient. If <integer1> and <integer2> are the same sign, then
  mod() and remainder() are equivalent.

  For example, division of -9 by 5 would give -1 by this definition
  instead of -2. idiv() would return -1. floordiv() would return -2,
  and so, the remainder() function properly goes with the idiv()
  function:

    idiv(x,y)*y + remainder(x,y) ==> x

  For positive x, remainder(x,y) always returns a positive number less
  than y. For negative x, remainder(x,y) always returns a negative
  number greater than y.

  remainder() is the usually the way the '%' operator in the C
   programming language is defined.

  Example:
    > say remainder(-9,5)
    You say "-4"
    > say remainder(-9,-5)
    You say "-4"
    > say remainder(17,3)
    You say "2"
    > say remainder(18,3)
    You say "0"

  A side effect function that has the same effect as @remit <room> =
  <message>.

  Related Topics: @remit.

& REMOVE()
REMOVE()

  FUNCTION: remove(<list>, <word>[, <delim>])

  Remove takes a list and a word, and returns the list, with the word deleted
  from it.  <delim> may be used to specify a delimiter other than a space.

  Example:
    > say remove(this is a test, is)
    You say "this a test"
    > say remove(You can't remove, this)
    You say "You can't remove"
    > say remove(You can't remove multiple words, You can't)
    You say "#-1 CAN ONLY DELETE ONE ELEMENT"
    > say remove(How about an o-separated list, w ab, o)
    You say "Hout an o-separated list"

& REPEAT()
REPEAT()

  FUNCTION: repeat(<string>,<number>)

  This function simply repeats <string>, <number> times.  No spaces are
  inserted between each repetition.

  Example:
    > say repeat(Test, 5)
    You say, "TestTestTestTestTest"

  Related Topics:

& REPLACE()
REPLACE()

  FUNCTION: replace(<list>, <pos>, <word>[, <delim>])

  This function inserts a word into <list> so that the word becomes the
  <pos>'th element of the list, and the word previously in that position
  is removed.  This means that it appears between the <pos-1>'th and
  <pos+1>'th elements of the original list, replacing the word at that
  position.  This function may not be used to append a word to a list.

  <delim> may be used to specify a delimiter other than a space.

  Examples:
    > say replace(This is a test, 4, quiz)
    You say "This is a quiz"
    > say replace(Yet@Another@Mundane@List, 3, Funky, @)
    You say "Yet@Another@Funky@List"

  Related Topics: extract(), insert(), ldelete().

& REST()
REST()

  FUNCTION: rest(<string>[, <delim>])

  The rest function takes a string, returns all the string except the first
  word, that is, everything to the right of the first space, or an empty
  string, or the empty string if there are no spaces in the string.

  <delim> may be used to specify a word delimiter other than a space.

  Example:
    > say rest(This is a test)
    You say "is a test"
    > say rest(Would you like coffee, or perhaps tea)
    You say "you like coffee, or perhaps tea"
    > say rest(List!with!different!delimiters,!)
    You say "with!different!delimiters"

& REVERSE()
REVERSE()

  FUNCTION: reverse(<string>)

  Reverses the order of the characters of <string>.

  Examples:
    > say reverse(This is a test)
    You say "tset a si sihT"
    > say reverse(This is a test, Really...)
    You say "...yllaeR ,tset a si sihT"
    > say reverse(A man, a plan, a canal -- Panama!)
    You say "!amanaP -- lanac a ,nalp a ,nam A"

  Related Topics: revwords().

& REVWORDS()
REVWORDS()

  FUNCTION: revwords(<string>[, <delim>])

  Reverses the order of the words of <string>.  A word is considered to be
  any sequence of nonblank characters, separated by blanks, so punctuation
  characters that follow a word are considered part of the word.

  <delim> may be used to specify a delimiter other than a space.

  Examples:
    > say revwords(This is a test. Really...)
    You say "Really... test. a is This"
    > say revwords(Was it a cat I saw?)
    You say "saw? I cat a it Was"

& RIGHT()
RIGHT()

  FUNCTION: right(<string>, <length>)

  This returns the right-most <length> characters from the <string>.

  If you are looking for left(), the corresponding function to right(), then
  look at strtrunc() as an equivalent.

  Related Topics: mid(), strtrunc().

& RJUST()
RJUST()

  FUNCTION: rjust(<string>, <width>[, <fill>])

  This function right-justifies <string> within a <width>-sized field. That
  is, it positions <string> visually in the right-most part of a
  <width>-sized field.

  The background of this field is specified by a repeating pattern of <fill>
  characters. The origin of this repeating pattern is at the first position
  of the field. Another way of saying this is that the repeating pattern
  starts in first position and repeats to the right. The last <fill> pattern
  may be truncated.

  By default, <fill> is a single, normal-colored space. The color of
  <string> and <fill> is maintained.

  If the visual width of <string> is longer than <width> characters, it is
  truncated to fit.

  Examples:
    > say -[rjust(foo,6)]-
    You say "-   foo-"
    > say %r0[rjust(foo,6)]7%r01234567
    You say "
    0   foo7
    01234567"
    > say =[rjust(bar,5,.)]=
    You say "=..bar="
    > say rjust(%xh%xrR%xgG%xbB,31,%xy--%xm+)
    --+--+--+--+--+--+--+--+--+-RGB

  Related Topics: center(), ljust().

& RLOC()
RLOC()

  FUNCTION: rloc(<object>,<levels>)

  This function may be used to get the location of an object's location
  (for which you would previously use 'loc(loc(<object>))', which fails if you
  don't control <object>'s location).  <levels> indicates the number of
  nested 'loc' calls to make, so 'loc(loc(<object>))' could be replaced with
  'rloc(<object>,2)'.  If rloc() encounters a room, the dbref of the room
  is returned.

  You must either control the object or be nearby for it to work.  When used
  on an exit it returns the destination of the exit.  You can also use rloc()
  to find the location of players that are not set UNFINDABLE.

  rloc(<object>,0) is the same as num(<object>), and rloc(<object>,1) is the
  same as loc(<object>).

  If set on a player, indicates that the player is a robot and is allowed to
  use the OUTPUTPREFIX and OUTPUTSUFFIX commands that many publicly available
  robot programs require.  Some MUXes do not restrict access to the
  OUTPUTPREFIX and OUTPUTSUFFIX commands.

  If set on an exit or a thing, indicates that robot players may not use the
  exit or pick up the thing, the player is treated as having failed the lock.

  Returns the number of the room that <obj> is in, or would be in if it
  executed LEAVE commands until it got to a room.  You can find out the
  containing room of objects you own, nearby objects, and findable players.

  Example:
    > i

S()

  FUNCTION: s(string)

  This function performs pronoun substitution in a string, and then returns
  that string.  As usually, %n is the name, %s the subjective pronoun, %o the
  objective, %p the possessive, and %a the absolute possessive.  It is
  important to note that the pronoun is that of the triggering object.

  So, if the ve of an object were: "[s(This is %n)], and I were to
  type @trigger <object>/ve, it would return "This is <myname>", but
  if vf were @trigger me/ve, then triggering the vf makes the ve
  return "This is <object>"

& SEARCH CLASSES
SEARCH CLASSES

  You may use the following classes in @search commands and search()
  function calls:

  TYPE      - Restricts to objects of the indicated type (OBJECTS, ROOMS,
              EXITS, PLAYERS, GARBAGE).  THINGS may be used as an alias for
              OBJECTS.
  NAME      - Restricts to objects whose names start with <restriction>.
  OBJECTS   - A combination of TYPE=OBJECT and NAME=<restriction>.
  THINGS    - An alias for OBJECTS.
  ROOMS     - A combination of TYPE=ROOM and NAME=<restriction>.
  EXITS     - A combination of TYPE=EXIT and NAME=<restriction>.
  PLAYERS   - A combination of TYPE=PLAYER and NAME=<restriction>.
  FLAGS     - Restricts to objects which have the flags listed in
              <restriction> set..
  POWER     - Restricts to objects which have the specified power.
  EVAL      - Evaluates the restriction for each object, replacing ##
              with the object's database number.  Evaluations that return
              TRUE (ie, not 0 or #-1) are selected.
  ZONE      - Restricts to objects that are in the indicated zone.

  EEXIT     - A combination of TYPE=EXIT and EVAL=<restriction>.
  EPLAYER   - A combination of TYPE=PLAYER and EVAL=<restriction>.
  PARENT    - Restricts to the parent designated by <restriction>.
  ZONE      - Restricts to the zone designated by <restriction>.

& SEARCH()
SEARCH()

  FUNCTION: search([<player>] [<class>=<restriction>[,<low>[,<high>]]])

  The search() function returns a list of objects that match the search
  criteria, which are the same as with the @search command.  This function
  costs as much as the @search command, so repeated use is expensive.

  Caution: if you use the [ and ] characters in an Eval selection you will
  need to escape them.

  Examples:
    > say search()
    You say "#226 #289 #325 #364 #368 #369"
    > @stats me
    6 objects = 0 rooms, 0 exits, 5 things, 1 players. (0 garbage)
    > say search(eval=\[eq(money(##),1)\])
    You say "#289 #325 #364 #368 #369"
    > say search(player=wizard)
    You say "#1"

& SECS()
SECS()

  FUNCTION: secs([<zonename>][, <precision>])

  The optional <zonename> parameter may be "utc" or "local". If no
  <zonename> is given, "utc" is assumed.

    local - Returns an integer which corresponds to the current local
            time on the machine running the MUX. This integer is
            affected by timezones and daylight savings time and is
            therefore primarily useful in conjunction with
            convsecs(..,utc).

    utc   - Returns the number of seconds (not counting leap seconds)
            since Jan 01 00:00:00 1970 UTC. This count of seconds is
            not affected by timezone or daylight savings time and is
            useful for calculating durations between two absolute
            points in time.

  <precision> determines the number of fractional seconds shown.
  By default, no fractional seconds are shown.

  Example:
     > say secs()
     You say "957557434"
     ... wait a bit ...
     > say secs()
     You say "957557447"
     > say secs(local,5)
     You say "957532580.09348"

  Related Topics: convsecs(), convtime(), time().

& SECURE()
SECURE()

  FUNCTION: secure(<string>)

  Returns <string> after replacing the characters [](){};%\$ with spaces.
  This prevents strings entered by players from causing undesired side
  effects when used, such as making your object perform unintended commands
  or give out information to which you have access.  Note that this function
  is only needed when the resulting string is to be passed through the @force
  command or be used as an attribute for an object (like the success message
  for a mail message object).

    > @va me=Sneak a peek at Wiz's desc... [get(#1/desc)]
    > say secure(%va)
    You say "Sneak a peek at Wiz's desc...  get #1/desc  "
    > say secure($foobar:this {is} a really, tough ; test.)
    You say " foobar:this is a really tough   test."

  Note: 'say secure(Sneak a peek at Wiz's desc... [get(#1/desc)])' does not
  produce the expected result because the argument is evaluated BEFORE being
  processed by secure(), therefore the [get()] call has already been
  performed.

& SEMAPHORES
SEMAPHORES

  Semaphores may be used for synchronizing complex objects or for enforcing
  mutual exclusion.  You may use any object you own or any LINK_OK object as
  a semaphore, and any type of object (thing, room, player, or exit) may be
  used.

  The semaphore state of an object is shown by the Semaphore attribute (which
  is read-only); a positive number indicates the number of commands awaiting
  notifies, and a negative number indicates the number of waits on that
  semaphore that will not block.

  Use the '@wait <object>' form of the @wait command to request a command be
  delayed until <object> is notified with the @notify command.  The @drain
  and @notify/all commands clear the semaphore on <object>, either
  discarding or executing all pending commands.  Remember that the
  object performing the @wait executes the command, not the object used
  as a semaphore.

{ 'help semaphores2' for more }

& semaphores2
SEMAPHORES (continued)

  You may also combine the semaphore and timer options of @wait with
  '@wait <object>/<timeout> = <command>'  If the time period expires before
  the semaphore is notified, then the command is executed and the semaphore
  count is decremented, just as if the command had been run because the
  semaphore had been notified.

  Examples: <simple>     @wait semaphore="Foo
                         @notify semaphore
            <mutex lock> @va mutex lock=@wait me=@trig me/vb
                         @vb mutex lock="Got it!;@notify me
                         @startup mutex lock=@notify me
            <timed wait> @wait timer/60 = "Sixty Second Timer.

  In the above examples you will say "Foo" after semaphore is notified,
  you will say "Got it" when you have the mutual exclusion lock mutex lock
  (You could have also modified object registers that need to be protected
  from concurrent update), and you will say "Sixty Second Timer." either when
  timer is notified or after sixty seconds pass.

  Related Topics: @drain, @notify, @wait.

& SESSION
SESSION

  COMMAND: session

  Displays information on how many characters you have sent and received
  during this session, and which (Internal) port you are connected to on the
  MUX.

  Example:
    > session
                                     Characters Input----  Characters Output---
    Player Name     On For Idle Port Pend  Lost     Total  Pend  Lost     Total
    Mortal           00:06   0s   16    0     0        44   156     0      2679
    2 Players logged in.

  Pending characters are those waiting to be acted on as commands (for input)
  or waiting to be sent out over the network (output).  Lost characters are
  due to overflowing either the MUX's input or output buffers, either as the
  result of running a single command that produces too much output (such as
  @find and @search commands that match a large number of objects), or from
  typing too much on one line.

  Note: your Pending count for output will always be nonzero, as the output
  of the SESSION command hasn't been sent out over the network yet.

& SET()
SET()

  FUNCTION: set(<name>, <string>)

  Works the same as @set, <name> and <string> are equivalent to what comes
  before and after the '=' sign. Returns nothing. This is a side effect
  function, and should only be used when necessary.

  Related Topics: @set

& SETDIFF()
SETDIFF()

  FUNCTION: setdiff(<list1>, <list2>[[, <delim>], <output delim>])

  This function returns the difference of two sets -- i.e., the elements in
  <list1> that aren't in <list2>. The list that is returned is sorted.

  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.

  Example:
    > say setdiff(foo baz gleep bar, bar moof gleep)
    You say, "baz foo"

  Related Topics: setinter(), setunion(), sort().

& SETINTER()
SETINTER()

  FUNCTION: setinter(<list1>, <list2>[[, <delim>], <output delim>])

  This function returns the intersection of two sets -- i.e., the elements
  that are in both <list1> and <list2>. The list that is returned is sorted.

  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.

  Example:
    > say setinter(foo baz gleep bar, bar moof gleep)
    You say, "bar gleep"

  Related Topics: setdiff(), setunion(), sort().

& SETQ()
SETQ()

  FUNCTION: setq(<number>,<string>)

  The setq() function is used to copy strings into local registers.
  It returns a null string; it is a purely "side effect" function.

  There are thirty-six local registers, numbered 0 through 9 and A
  through Z. They are cleared at the start of each interactive
  command, but are preserved across the command queue. They are most
  useful for storing complex function evaluations which are used
  repeatedly within a single command.  The local registers may be read
  via the r() function, and a common use of setq()/r() is to
  temporarily store the result of a complex evaluation whose result is
  needed more than once.

  setq() can be used to improve the readability of MUX code, as well as to
  cut down the amount of time needed to do complex evaluations.

  Example:
    > &TEST me=Test on [mudname()] at [time()].
    > say [setq(0,u(TEST))]'[r(0)]' has length [strlen(r(0))].
    You say "'Test on TestMUX at Tue Feb 23 17:00:51 1993.' has length 45."

  Related Topics: r(), setr().

& SETR()
SETR()

  FUNCTION: setr(<number>,<string>)

  This function is identical to setq(), but returns <string>.

  Related Topics: setq(), r().

& SETUNION()
SETUNION()

  FUNCTION: setunion(<list1>, <list2>[[, <delim>], <output delim>])

  This function returns the union of two sets -- i.e., all the elements of
  both <list1> and <list2>, minus any duplicate elements. Think of it as
  CAT() without duplicated words.  The list returned is sorted.

  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.

  Example:
    > say setunion(foo baz gleep bar, bar moof gleep)
    You say, "bar baz foo gleep moof"
    > say setunion(foo|bar|foo,,|,.)
    You say, "bar.foo"

& SHA1()
SHA1()

  FUNCTION: sha1(<string>)

  Returns 40 hexadecimal characters which represent a 160-bit
  cryptographically secure hash of <string>.

  This hash can also be described as a signature, fingerprint, or
  digest.  sha1() implements SHA-1 as described in FIPS 180-1 and
  FIPS 180-2.

& SORT()
SORT()

  FUNCTION: sort(<list>[, <sort type>[, <idelim>[, <odelim>]]])

  Takes a list of words, numbers or dbrefs, and sorts them into ascending
  order.  By default, lexicographic order is used for words, and numeric
  order is used for numbers and dbrefs.

  <sort type> may be used to specify the type of sort to perform (use 'd' for
  dbref, 'n' for integer numeric, 'f' for floating numeric, and 'a' for
  alphanumeric).  If omitted or left blank, the sort() function will
  try to determine the type of sort to perform automatically.

  By default, the output delimiter, <odelim>, defaults to the input delimiter,
  <idelim>, which itself defaults to a space. Delimiters here, like most other
  functions, are used to separate items in a list.

  Examples:
    > say sort(This is a test)
    You say "This a is test"
    > say sort(98 100 99 101,n)
    You say "98 99 100 101"
    > say sort(foo-bar-bletch,,-,|)
    You say "bar|bletch|foo"

  Related Topics: munge, sortby

& SORTBY()
SORTBY()

  FUNCTION: sortby([<obj>/]<attrib>,<list>[,<delimiter>])

  This sorts an arbitrary list according to the u-function <obj>/<attrib>.
  This u-function should compare two arbitrary elements, %0 and %1, and
  return zero (equal), a negative integer (element 1 is less than element 2)
  or a positive integer (element 1 is greater than element 2).

  A simple example, which imitates a normal alphabetic sort:
    > &ALPHASORT test=[comp(%0,%1)]
    > say [sortby(test/ALPHASORT,foo bar baz)]
    You say "bar baz foo"

  A slightly more complicated sort. #1 is "God", #2 is "Amby", "#3" is "Bob":
    > &NAMESORT me=[comp(name(%0),name(%1))]
    > say [sortby(NAMESORT,#1 #2 #3)]
    You say "#2 #3 #1"

  Warning: the function invocation limit applies to this function. If
  this limit is exceeded, the function will fail _silently_. List and
  function sizes should be kept reasonable.

& SPACE()
SPACE()

  FUNCTION: space(<count>)

  Returns the number of indicated spaces.  If <count> is missing, negative,
  or cannot be converted to a number, one space is returned.  This function
  is useful when you want to pass a single space (or more than one) as a
  function to an argument, because normally leading and trailing spaces are
  stripped from function arguments.

  Examples:
    > say space(4)
    You say "    "
    > say edit(Foo bar bletch, space(), X)
    You say "FooXbarXbletch"

& SPLICE()
SPLICE()

  FUNCTION: splice(<list1>, <list2>, <word>[, <delim>])

  This function splices <list1> and <list2> together. <list1> and <list2>
  are space-separated lists of words

  If a word in <list1> is the same as <word>, it is replaced by the word
  in the corresponding position in <list2>.  Both lists must have the
  same number of words.

  <delim> may be used to specify a delimiter other than a space.

  Example:
    > say splice(foo bar baz,eek moof gleep,bar)
    You say, "foo moof baz"

& SPOOFING
SPOOFING

  Spoofing is the act of making other characters think that a person said or
  did something that they did not.  This is very easy to accomplish, and has
  some good effects, which is why it is allowed.  Note that the NOSPOOF flag
  allows players to see exactly who is spoofing what.

  Example:
    ... From TinyJerk's perspective ...
    > @emit Wizard is a jerk!
    Wizard is a jerk.

   ... From Wizard's perspective, Wizard is set NOSPOOF ...
   [TinyJerk(#226)] Wizard is a jerk!
   > @boot tinyjerk
   You booted TinyJerk off!
   TinyJerk has disconnected.
   1 connection closed.

   ... TinyJerk's perspective again ...
   Wizard gently shows you the door.

& SQRT()
SQRT()

  FUNCTION: sqrt(<number>)

  Returns the square root of <number>.  <number> may be a floating point
  number, and a floating point result is returned.  <number> may not be
  negative.

  Examples:
    > say sqrt(2)
    You say "1.414214"
    > say sqrt(100)
    You say "10"
    > say sqrt(0)

& SQUISH()
SQUISH()

  FUNCTION: squish(<text>[,<character>])

  This function replaces multiple occurrences of <character> in <text> with a
  single occurrence.  If <character> is not specified, it defaults to a space.

  Examples:
    > @wait 0=@va me=Foo[space(5)]Bar
    Set.
    > think %va
    Test     Test
    > say squish(%va)

& STACK
STACK

  Command lists that are run on objects can have up to 10 stack values
  named %0 through %9 (or [v(0)] through [v(9)]).  Stack values can be set
  by the @trigger command, or by matching wildcard characters in the Listen
  attribute (in the case of the Ahear, Aahear, and Amhear attributes).

  Example:
    > @listen item = * foo *
    Set.
    > @ahear item = "-->[v(1)]<-- bar -->[v(0)]<--
    Set.
    > say Fee fie foo fum

& STARTSECS()
STARTSECS()

  FUNCTION: startsecs()

  Returns the number of seconds that represents the time the MUX last
  rebooted. The time is measured in the same way as the secs()
  function. This is easier and more efficient than using
  convtime(starttime()).

  Example:
    > say startsecs()
    You say "959093815"

& STARTTIME()
STARTTIME()

  FUNCTION: starttime()

  Returns a string which is the time the MUX last rebooted.  The time
  is in the same format as the TIME() function returns.

  Example:
    > say starttime()
    You say "Sat Dec  7 00:09:13 1991

  Related Topics: convtime().

& STATS()
STATS()

  FUNCTION: stats([<player>])

  This function returns information about the number of objects on the MUX,
  much like the @stats command.  If the argument is omitted or is 'all', then
  the stats for the entire MUX are returned, otherwise the stats for the
  named player are returned.  You can only get stats for yourself.

  The stats are returned as a set of 6 numbers, in the same order as reported
  by the @stats command: total objects, rooms, exits, things, players, and
  garbage.  This command costs as much as the equivalent @stats command (ie:
  '@stats/all' or '@stats <player>', not the free '@stats').

  Examples:
    > @stats me
    6 objects = 0 rooms, 0 exits, 5 things, 1 players. (0 garbage)
    > say stats(me)
    You say "6 0 0 5 1 0"
    > say stats()
    You say "377 51 165 134 20 7"
    > @stats/all
    377 objects = 51 rooms, 165 exits, 134 things, 20 players. (7 garbage)

& STRIP()
STRIP()

  FUNCTION: strip(<string1>[,<string2>])
  
  This function strips out every occurrence of every character of <string2>
  from <string1> and returns <string1>.  If <string2> is empty or not given,
  <string1> is returned, stripped of ANSI codes. The strip function is case
  sensitive.
  
  Examples:
    > say strip(This is a test,is)
    You say "Th  a tet"
    > say strip(abcdefgABCDEFG,azGy!7$B)
    You say "bcdefgACDEF"

& STRMATCH()
STRMATCH()

  FUNCTION: strmatch(<string>,<pattern>)

  This function matches <pattern> against the entire <string>, returning 1
  if it matches and 0 if it does not.  The case of the characters being
  matched is not significant.

  The pattern may contain the wildcards '*' and '?'.  '?' matches any one
  character, while '*' matches any number of characters, including none.
  So 's?x' would match 'sex' or 'six', but not to 'socx', but 's*x' would
  match any of them.

  Examples:
    > say strmatch(This is a test,*Test)
    You say "1"
    > say strmatch(This is a test,*This)
    You say "0"
    > say strmatch(This is a test,*is*is*)
    You say "1"

& STRTRUNC()
STRTRUNC()

  FUNCTION: strtrunc(<string>,<number>)

  Much more efficient than the equivalent mid().

  Related Topics: mid(), ljust().

& SUB()
SUB()

  FUNCTION: sub(<number1>,<number2>)

  Returns the result of subtracting <number2> from <number1>.

& SUBEVAL()
SUBEVAL()

  FUNCTION: subeval(<string>)

  This function's usefulness is primarily useful in conjunction with
  v() as a way to control when evaluation occurs. Escapes are
  evaluated, but {} and functions are not. The location escape is also
  not evaluated.

  When used from the command line, it's use is limited to nil because
  evaluation of subeval's parameters occurs before the subeval()
  function is called.

& SUBJ()
SUBJ()

  FUNCTION: subj(<object>)

  Returns the proper subjective pronoun (he, she, it, they) for referring to
  <object>, based on the object's Sex attribute.  You must either control
  or be near <object>.

  Related Topics: aposs(), obj(), poss(), SUBSTITUTIONS.

& SUBSTITUTIONS
SUBSTITUTIONS

  The most basic form of evaluation is a %-substitution.  Even when other
  forms of evalution are not performed, %-substitutions usually are.  A
  %-substitution is a '%' followed by one or two letters, digits, or symbols.
  If a sequence is understood, it is substituted by a corresponding value.
  If a sequence is not understood, the initial '%' is removed.  In this way,
  the '%' also acts similiarly to the '\' escape.

  For some substitutions, if the letter following the '%' is capitalized, the
  first letter of the result of the substitution is also capitalized.

  Certain %-sequences provide gender-specific pronouns.  Some provide
  information about the execution state.  Some provide control over the
  appearance of text.

  Commonly-used substitutions:

    %r       Carriage Return
    %t       Tab
    %b       Space
    %%       Literal '%'.
    %\       Literal '/'.

& SWITCH()
SWITCH()

  FUNCTION: switch(<str>[,<pat1>,<res1>]...[,<dflt>])

  The switch function compares <str> against each pattern, <patI>,
  returning the result, <resI> that corresponds to the first pattern that
  matches <str>. If none match, then the default result, <dflt>, is
  returned.

  Before <resI> is evaluated for return, #$ is substituted with the value
  of <str>. In this way, the code in <resI> has a short-hand way of getting
  at the <str> that matched it's corresponding pattern.

  Patterns may include * and ?. * matches any number of characters, and ?
  matches any 1 character. Instead of pattern matching, it is also possible
  to compare the alphabetic or numeric value of <str> with <pat> by using
  the < and > operators.

  Example:
    > say switch(c,*a*,A,*b*,B,*c*,C,*d*,D,E)
    You say "C"
    > say switch(f,*a*,A,*b*,B,*c*,C,*d*,D,E)

           take[/<switch>] <object>'s <sub-object>

  The first form picks up <object> from your location and adds it to your
  inventory.  It will fail if the object is locked against you, or if you
  are inside a player or object that you don't control and which isn't
  set ENTER_OK.

  The second form takes an exit from your location and adds it to you.
  Anyone inside you may then use the exit to travel to the exit's destination.
  You may take exits that you own, and exits owned by others in locations that
  you own.

  The third form takes <sub-object> from <object> and adds it to your

  sends it home, and dropping a thing in a room with a drop-to sends the
  thing to the drop-to location.

  The second form removes <exit> from your list of exits and adds it to the
  list of exits for the current location.  Anyone in the same location as
  you may then use the exit to travel to the exit's destination.  You can
  only drop exits when you own the location where you are dropping them.

  The following switch is recognized:
     /quiet   - Don't perform the @odrop/@adrop attributes on the dropped
                 object.  This switch only works if you control the object.

  'drop' is the same as 'throw'.

& TIME()
TIME()

  FUNCTION: time([<zonename>][, <precision>])

  The optional <zonename> parameter may be "utc" or "local". If no
  <zonename> is given, "local" is assumed.

    local - Gives you the current local time string of the machine the
            MUX is running on. This time is affected by the daylight
            savings time (or 'summer') rules in force at the server's
            location.

    utc   - Gives you the time string for the UTC time zone.

  <precision> determines the number of fractional seconds shown.
  By default, no fractional seconds are shown.

  Example:
    > say time()
    You say "Fri May 05 13:05:39 2000"
    > say time(utc,3)
    You say "Fri May 05 20:05:39.667 2000"

& TRACE
TRACE

  FLAG: TRACE(T)  ()

  When a thing is set TRACE, it will report to its owner the result of all
  substitutions that it performs that change the original string.  The order
  for displaying nested evaluations (such as when evaluating the arguments to
  a function) is a site-selected configuration parameter.

  Example:
    > @set object = trace
    > @va object = say The result is [add(4,mul(3,%0))].
    > @trig object/va = 7
      object(#322)} '%0' -> '7'
      object(#322)} 'mul(3,%0)' -> '21'
      object(#322)} 'add(4,mul(3,%0))' -> '25'
      object(#322)} 'The result is [add(4,mul(3,%0))].' -> 'The result is 25.'
      object says "The result is 25."

{ 'help trace2' for more }

& TRACE2
TRACE (continued)

  When trace output is displayed in top-down order (final evaluation first,
  followed by the 'smaller' evaluations needed to perform it), then the total
  number of trace output lines that may be produced by an evaluation is limited
  to 200.  Bottom-up trace output is not limited.

& TRAIN
TRAIN

  COMMAND: train <command>

  The train command is used to output to your location exactly what you
  have typed, then execute it.  The output is not parsed and is taken
  verbatim and displayed as is. 

  Example:
    > train @emit To do addition, type:  say add(1,1) = 2
    YourName types -=> @emit To do addition, type: say add(1,1) = 2
    To do addition, type: say add(1,1) = 2

& TRANSLATE()
TRANSLATE()

  FUNCTION: translate(<string>, <type>)

  This function converts all raw ANSI color codes, carriage returns, and tabs
  to either MUX substitutions or to spaces.  If <type> is 0 or 's', the raw
  codes are converted to spaces, if it is 1 or 'p', the codes are converted
  to MUX %c and %r substitutions.

  Because multiple spaces can be compressed into a single space, if <type> is
  1 or 'p', multiple spaces are converted to a series of '%b' followed by a
  single space.

  FLAG: TRANSPARENT(t)  ()

  If an exit is TRANSPARENT, then when you look at it you see the description
  of the room on the other side of the exit in addition to the description
  of the exit. When a room is TRANSPARENT, you see a 'long' listing of
  exits, including their destinations.

& TRIM()
TRIM()

  FUNCTION: trim(<string> [,<trim style> [,<trim character>]])

  This function will trim trailing and/or lead characters on the string
  that you specify.  <trim character> specifies the character to trim (default
  is space), and <trim style> tells the kind of trimming to perform (default
  is trim both sides of the string).

  The following values for <trim style> are recognized:
      'b' :   Trim both ends of the string (default)
      'l' :   Trim the left end of the string.
      'r' :   Trim the right end of the string.
  Note: anything else specified for <trim style> will trim both sides.

  Example:
    > say trim(;;;Wacka;;;,,;)
    You say "Wacka"
    > say trim(%b%b%b Polly Parrot %b%b%b%b,r)
    You say "    Polly Parrot"
    > say trim(---Trim Rules!---,l,-)
    You say "Trim Rules!---"

& TRUNC()
TRUNC()

  FUNCTION: trunc(<number>)

  Returns the value of <number> after truncating off any fractional value.
  <number> may be a floating point number, and an integer result is returned.

  Examples:
    > say trunc(5)
    You say "5"
    > say trunc(5.2)
    You say "5"
    > say trunc(5.8)
    You say "5"
    > say trunc(-5)
    You say "-5"
    > say trunc(-5.2)
    You say "-5"

    You say "PLAYER"
    > say type(here)
    You say "ROOM"

& U()
U()

  FUNCTION: u([<obj>/]<attr>[,<arg>]...)

  The u function evaluates an attribute, either from the object performing the
  function or from another object you own, passing in arguments and returning
  the result.

  When evaluating the fetched attribute, %# refers to the original enactor and
  not the 'calling' object, and 'me' refers to the object that supplied the
  attribute.

  Examples:
    > @va me=Word is [extract(v(vb),add(%0,1),1)], arg2 is %1.
    > @vb me=This is a test of the u function.
    > say u(va,4,Testing 123)
    You say "Word is of, arg2 is Testing 123."
    > say u(va,7)
    You say "Word is function., arg2 is ."
    > say u(me/va,6,Foobar)
    You say "Word is u, arg2 is Foobar."

  Related Topics: s(), v(), get(), get_eval(), map(), ulocal().

& UCSTR()
UCSTR()

  FUNCTION: ucstr(<string>)

  Returns <string> with all letters converted to uppercase.

  Example:
    > say ucstr(This is a test, really!)
    You say "THIS IS A TEST, REALLY!"

  Related Topics: capstr(), lcstr().

& UDEFAULT()
UDEFAULT()

  FUNCTION: udefault([<obj>/]<attr>,<default case>[,<arg>]...)

  This function returns the value of the user-defined function
  as defined by <attr> (or <obj>/<attr>), as if retrieved via
  the u() function, with <args>, if the attribute exists and is
  readable by you.

  Otherwise, it evaluates the default case, and returns that. The
  default case is only evaluated if the attribute does not exist
  or cannot be read.

  Examples:
    > &TEST me=[center(%0,5,*)]
    > say udefault(Test,-- BOOM --,ACK)
    You say "*ACK*"
    > &TEST me
    > say udefault(me/Test,-- BOOM --,ACK)
    You say "-- BOOM --"

  Related Topics: get(), get_eval(), u(), default(), edefault().

& ULOCAL()
ULOCAL()

  FUNCTION: ulocal([<obj>/]<attr>[,<arg>]...)

  The ulocal() function is almost identical to u() in function:  it
  evaluates an attribute, either from the object performing the function,
  or another object that you control or has the same owner as you, passing
  in arguments and returning the result. When evaluating the fetched
  attribute, %# refers to the original enactor and not the 'calling' object;
  'me' refers to the object that supplied the attribute.

  However, unlike the u() function, the global registers r(0) through
  r(9) and r(A) through r(Z) (%q0 - %q9, %qA - %qZ) are preserved in
  their initial state. This means that functions "below" the level of
  the u() can reset global registers for temporary calculations,
  without needing to worry about "clobbering" the original values.

  This makes ulocal() particularly useful for global or shared code which
  calls arbitrary u() functions, where global register values need to be
  preserved from accidental user clobbering.

  Related Topics: ulocal2

& ULOCAL2
ULOCAL() (continued)

  Examples:
    > &FRUIT me=apples bananas oranges pears
    > &SUB-FUNCTION me=[setq(0,v(FRUIT))][extract(%q0,match(%q0,%0),1)]
    > &TOP-FUNCTION me=[setq(0,are delicious!)][ulocal(SUB-FUNCTION,%0)] %q0
    > say u(TOP-FUNCTION,b*)
    You say "bananas are delicious!"

  If SUB-FUNCTION had been called with u() instead of ulocal():
    > &TOP-FUNCTION me=[setq(0,are delicious!)][u(SUB-FUNCTION,%0)] %q0
    > say u(TOP-FUNCTION,b*)
    You say "bananas apples bananas oranges pears"

  In this second example, in SUB-FUNCTION, %q0 was set to "apples bananas
  oranges pears", so that when the u() "returned" and TOP-FUNCTION evaluated
  %q0, this is what was printed. In the first example, ulocal() reset the
  value of %q0 to its original "are delicious!"

& V()
V()

  FUNCTION: v(<string>)

  The V function can be used as an alternative for percent (%) substitution
  and also as a replacement for get(me/<arg>).  If the argument is two
  characters long or longer and starts with a letter, then the object
  performing the v() call (and its parent, if necessary) is searched for the
  named attribute, and its value is returned if possible.  Otherwise, a
  percent substitution is performed on the argument (so that v(o) is
  equivalent to %o, for instance).  The percent form (%o in the previous
  example) is preferred as it is faster, and there are no longer any security
  problems associated with it.  Note that attributes with single-character
  names cannot be retrieved with v().

VALID()

  FUNCTION: valid(<category>,<argument>)

  This returns true or false depending on whether the characters and
  arrangement of characters in <argument> satisfy the restrictions implied by
  <category>.

  Possible values for <category>:

     name        Test for object name.
     playername  Test for player name.
     attrname    Test for attribute name.

  Valid() does not check the database for existence and it does not guarantee
  that an attempt to use such an object will succeed. It only looks at
  <argument> as a string of characters.

& VCROSS()
VCROSS()

  FUNCTION: vcross(<vector>,<vector>[,<delim>][,<output delim>])

  Returns the cross product of two vectors. The cross product of two

VERBS

  For many verbs there are three attributes that specify messages and actions
  associated with the verb in addition to the verb's builtin action.
  The attributes are named Verb, Overb, and Averb.  Verb is the message that
  the enactor sees, Overb is the message that everyone else in the same room
  as the enactor sees, and Averb is a list of commands that are run.
  These attributes may be set using the @<attribute> command, so the commands
  to set the attributes related to the 'drop' command are @drop, @odrop, and

WRAP()

  FUNCTION: wrap(<text>,<width>[,<just>,[<lefttxt>[,<righttxt>
                [,<hanging>[,<osep>[,<width1>]]]]]])

  This function word wraps the text to fit into a column of the specified
  width.  Words are separated by spaces. If a word in the text is longer than
  a single line, it is simply broken at the end of the line.  Tabs are
  expanded to 8 spaces, and %r's are treated as a force to the next line,
  overriding the logic of the word wrapping. 

  The <just> argument may be Left, Right, or Center. Only the first
  character of the argument is significant. <just> defaults to Left.

  The <lefttxt> and <righttxt> specify text to insert as borders on either
  side of each line. They default to nothing.

  The <hanging> argument specifies an optional number of spaces to insert on
  the left margin for any line that is not the first line. This is commonly
  called a hanging indent in word processing.  <osep> is the output separator,
  and it defaults to %r.  <width1> is the width of the first line (default of
  <width>).

  Examples:
  > @emit wrap(Hi there. How are you?, 10, right, |%b, %b|)
  |  Hi there. |
  |    How are |
  |       you? |

  > @emit DESC: [wrap(get(me/desc), 10, left,,,6)]
  DESC: You see 
        before 
        you a
        stranger.

  The width can not be above 4000 characters.

& WRITETIME()
WRITETIME()

  FUNCTION: writetime(<seconds>)

  This function converts seconds to a number of time elements (hours,
  minutes, seconds) that is equivalent to the given number of
  <seconds>.

  This is very similar to the exptime() function, but the elements
  are given their long names instead of short names.

  Example:
    > say writetime(45)
    You say "45 seconds"
    > say writetime(12345)
    You say "3 hours 25 minutes 45 seconds"
    > say writetime(123456)
    You say "1 day 10 hours 17 minutes 36 seconds"

ZONE()

  FUNCTION: zone(<object>)

  Returns the object's 'zone'. This is the dbref of the master object
  which defines the zone.

& ZONES
ZONES

  Zones are areas of the MUX which may be controlled by many people.
  Essentially, they allow group ownership of objects.

  The default zone is NOTHING. Any building done by a player defaults
  to belonging to the same zone that the player belongs to.
  Every zone is defined by a Zone Master Object (ZMO). The ZMO is an
  ordinary MUX object owned by some player. A wizard may change the
  zone of an object or player to a ZMO.

  If the ZMO is a room, it is called a "Parent room." Most of the
  statements about ZMOs also apply to parent rooms; for details,
  see the help topic PARENT ROOMS.

ZONES (continued)

  Anyone who can pass the Enter lock of the ZMO has control over all
  objects in that zone. This, in essence, gives that player wizard
  powers within that zone. For this reason, one must be extremely
  careful with the enter locks of ZMOs!

  Also, $commands on a ZMO are treated as global within that zone.
  The game attempts to match $commands for the ZMO of the player's
  location, as well as $commands for the player's own zone.
  For some suggestions on how to use zones, see "help ZONES3".

  Some suggested uses of zones:

    1. If you are working on a building project with several people, it
       may be useful to create a zone object and @elock it to all of you,
       and ask a wizard to @chzone the players involved to the zone object.
       That way, all of the players working on the project will be able to
       modify the building.

    2. On a similar thread, if several players are working on a project
       involving only a few objects, it may be simpler to create a zone
       object and @chzone those few objects to the ZMO instead of resetting
       the zones of the players. Note that a player does not have to belong
       to a zone in order to change objects in that zone; all is merely
       required to pass the ZMO's enter lock.

ZONES (continued)

  More possible uses for zones:

    3. If local wizards are desired, a zone object may be created and enter
       locked to the local wizard. Players building within that zone should
       be @chzone'd to that ZMO. The local wizard will then be able to
       control anything within that domain.

    4. If you want restricted global commands defined over only a small area,
       you can define that area to be part of a zone, and place the desired
       $commands upon the ZMO.

& ZWHO()

  FUNCTION: zwho(<object>)

  Returns a list of players who are a member of the zone defined by
