      <descr>
        <p>The system unit contains the standard supported functions of Free Pascal. It is the
same for all platforms. Basically it is the same as the system unit provided
with Borland or Turbo Pascal.
</p>
        <p>Functions are listed in alphabetical order. Arguments of functions or
procedures that are optional are put between square brackets.
</p>
        <p>The pre-defined constants and variables are listed in the first section.
The second section contains an overview of all functions, grouped by
functionality, and the last section contains the supported functions
and procedures.

File sharing is not taken into account when calling <var>Append</var>.

      <element name="Assert">
        <short>Check validity of a given condition.</short>
        <descr>With assertions on, <var>Assert</var> tests if <var>expr</var> is 
false, and if so, aborts the application with a Runtime error 
227 and an optional error message in <var>msg</var>.
If <var>expr</var> is true, program execution continues normally. 

If assertions are not enabled at compile time, this routine does 
nothing, and no code is generated for the <var>Assert</var> call. 

Enabling and disabling assertions at compile time is done via
the <var>\$C</var> or <var>\$ASSERTIONS</var> compiler switches. These are
global switches.

The default behavior of the assert call can be changed by 
setting a new handler in the <var>AssertErrorProc</var> variable.
Sysutils overrides the default handler to raise a <var>EAssertionFailed</var> 
exception.

However ord is not considered deprecated and remains in wide use today.

<var>L</var> must be between <var>0</var> and <var>Paramcount</var>,

</p>
          <p>The command-line parameters will be truncated to a length of 255,

The <var>Objpas</var> unit (used in <var>objfpc</var> or <var>delphi</var> mode)
defines versions of <var>Paramstr</var> which return the full-length command-line 
arguments, using ansistrings.
</p>
          <p>In the interest of portability, the <var>ParamStr</var> function tries to behave 
the same on all operating systems: like the original <var>ParamStr</var> function 
in Turbo Pascal. This means even on Unix, paramstr(0) returns the full 
path to the program executable. A notable exception is Mac OS X, where
the return value depends on how the application was started. It may be that 
just the name of the application is returned (in case of a command-line
launch)
</p>
          <p>In general, it's a bad idea to rely on the location of the binary. Often,
this goes against best OS practices. Configuration data should (or can) not
be stored next to the binary, but on designated locations. What locations
these are, is very much operating system dependent. Therefore, 
<var>ParamStr(0)</var> should be used with care.

        <descr>
          <var>Write</var> writes the contents of the variables <var>V1</var>, <var>V2</var> etc. to
the file <var>F</var>. <var>F</var> can be a typed file, or a <var>Text</var> file.
If <var>F</var> is a typed file, then the variables <var>V1</var>, <var>V2</var> etc. must
be of the same type as the type in the declaration of <var>F</var>. Untyped files
are not allowed.
If the parameter <var>F</var> is omitted, standard output is assumed.
If <var>F</var> is of type <var>Text</var>, then the necessary conversions are done
such that the output of the variables is in human-readable format.
This conversion is done for all numerical types. Strings are printed exactly
as they are in memory, as well as <var>PChar</var> types.
The format of the numerical conversions can be influenced through
the following modifiers:
<var>OutputVariable : NumChars [: Decimals ]  </var>
This will print the value of <var>OutputVariable</var> with a minimum of
<var>NumChars</var> characters, from which <var>Decimals</var> are reserved for the
decimals. If the number cannot be represented with <var>NumChars</var> characters,
<var>NumChars</var> will be increased, until the representation fits. If the
representation requires less than <var>NumChars</var> characters then the output
is filled up with spaces, to the left of the generated string, thus
resulting in a right-aligned representation.
If no formatting is specified, then the number is written using its natural
length, with nothing in front of it if it's positive, and a minus sign if
it's negative.
Real numbers are, by default, written in scientific notation.

            <var>Ptrint</var> is a signed integer type which has always the same size as a

code, because pointers are normally unsigned. For example, consider the following
code:
</p>
          <code>getmem(p,2048);                 {Assume the address of p becomes $7ffffff0.}
q:=pointer(ptrint(p)+1024));    {Overflow error.}
writeln(q&gt;p);                   {Incorrect answer.}
</code>
          <p>Ptrint might have a valid use when two pointers are substracted from each other if
it is unknown which pointer has the largest address. However, even in this case
ptrint causes trouble in case the distance is larger than high(ptrint) and must be
used with great care.

        <descr>
          <p>
            <var>TThreadManager</var> is a record that contains all callbacks needed for the thread handling
routines of the Free Pascal Run-Time Library. The thread manager can be set
by the <link id="SetThreadManager"/> procedure, and the current thread
manager can be retrieved with the <link id="GetThreadManager"/> procedure.
</p>
          <p>The Windows RTL will set the thread manager automatically to a system thread
manager, based on the Windows threading routines. Unix operating systems
provide a unit <file>cthreads</file> which implements threads based on the C
library POSIX thread routines. It is not included by default, because it
would make the system unit dependent on the C library.

Depending on the kind of resources (internal, external), another resource 
managing handler is installed by the system. The resource manager record is
used by all resource handling functions to do the actual work: for each
function in the API, a handler function is available. People wishing to
implement their own resource manager, must implement all handler functions
in their implementation.
</p>
          <p>As soon as resources are used, the compiler will install a resource manager,
depending on the platform, this may be an internal or an external resource
manager.
