\section switch switch - conditionally execute a block of commands

\subsection switch-synopsis Synopsis
 <tt>switch VALUE; [case [WILDCARD...]; [COMMANDS...];...] end</tt>

\subsection switch-description Description

The \c switch statement is used to perform one of several blocks of
commands depending on whether a specified value equals one of several
wildcarded values.

\subsection switch-example Example

If the variable \$animal contins the name of an animal, the
following code would attempt to classify it:

<p>
<tt>
<br>switch $animal;<br>
&nbsp;&nbsp;&nbsp;&nbsp;case cat;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo evil;<br>
&nbsp;&nbsp;&nbsp;&nbsp;case wolf dog human moose dolphin whale;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo mammal;<br>
&nbsp;&nbsp;&nbsp;&nbsp;case duck goose albatros;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo bird;<br>
&nbsp;&nbsp;&nbsp;&nbsp;case shark trout stingray;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo fish;
<br>end;
</tt>
</p>
<p>

If the above code was run with \$animal set to \c whale, the output
would be \c mammal.
