## Description

A `Screen` is a verbatim environment for displaying text that the user might see on a computer terminal. It is often used to display the results of a command.

Having less specific semantic overtones, `Screen` is often used wherever a verbatim presentation is desired, but the semantic of `ProgramListing` is inappropriate.

### Processing expectations

This element is displayed “verbatim”; whitespace and linebreaks within this element are significant. `Screen`s are usually displayed in a fixed width font.

### Future Changes

The `InterfaceDefinition` element will be discarded in DocBook V4.0. It will no longer be available in the content model of this element.

### Future Changes

The `xml:space` attribute is automatically provided in the XML DTD.

### Parents

These elements contain screen: `answer`, `appendix`, `article`, `bibliodiv`, `bibliography`, `blockquote`, `callout`, `caption`, `caution`, `chapter`, `colophon`, `constraintdef`, `dedication`, `entry`, `example`, `figure`, `footnote`, `glossary`, `glossdef`, `glossdiv`, `important`, `index`, `indexdiv`, `informalexample`, `informalfigure`, `itemizedlist`, `legalnotice`, `listitem`, `msgexplan`, `msgtext`, `note`, `orderedlist`, `para`, `partintro`, `preface`, `procedure`, `qandadiv`, `qandaset`, `question`, `refsect1`, `refsect2`, `refsect3`, `refsection`, `refsynopsisdiv`, `revdescription`, `screenco`, `sect1`, `sect2`, `sect3`, `sect4`, `sect5`, `section`, `setindex`, `sidebar`, `simplesect`, `step`, `textobject`, `tip`, `variablelist`, `warning`.

### Children

The following elements occur in screen: `abbrev`, `acronym`, `action`, `anchor`, `application`, `author`, `authorinitials`, `beginpage`, `citation`, `citerefentry`, `citetitle`, `classname`, `classsynopsis`, `cmdsynopsis`, `co`, `command`, `computeroutput`, `constant`, `constructorsynopsis`, `coref`, `corpauthor`, `database`, `destructorsynopsis`, `email`, `emphasis`, `envar`, `errorcode`, `errorname`, `errortext`, `errortype`, `exceptionname`, `fieldsynopsis`, `filename`, `firstterm`, `footnote`, `footnoteref`, `foreignphrase`, `funcsynopsis`, `function`, `glossterm`, `guibutton`, `guiicon`, `guilabel`, `guimenu`, `guimenuitem`, `guisubmenu`, `hardware`, `indexterm`, `inlineequation`, `inlinegraphic`, `inlinemediaobject`, `interface`, `interfacename`, `keycap`, `keycode`, `keycombo`, `keysym`, `lineannotation`, `link`, `literal`, `markup`, `medialabel`, `menuchoice`, `methodname`, `methodsynopsis`, `modespec`, `mousebutton`, `nonterminal`, `olink`, `ooclass`, `ooexception`, `oointerface`, `option`, `optional`, `othercredit`, `parameter`, `personname`, `phrase`, `productname`, `productnumber`, `prompt`, `property`, `quote`, `remark`, `replaceable`, `returnvalue`, `revhistory`, `sgmltag`, `structfield`, `structname`, `subscript`, `superscript`, `symbol`, `synopsis`, `systemitem`, `textobject`, `token`, `trademark`, `type`, `ulink`, `userinput`, `varname`, `wordasword`, `xref`.

## Attributes

format

  The `Format` attribute applies the `linespecific` notation to all `Screen`s. All white space and line breaks must be preserved.

linenumbering

  Line numbering indicates whether or not the lines of a `Screen` are to be automatically numbered. The details of numbering (every line or only selected lines, on the left or right, etc.) are left up to the processing application. Be aware that not all processors are capable of numbering lines.

width

  `Width` specifies the width (in characters) of the longest line in this `Screen` (formatters may use this value to determine scaling or rotation).

## See Also

`computeroutput`, `lineannotation`, `literallayout`, `programlisting`, `screenshot`, `synopsis`, `userinput`.
