ern body </I>?<I>pattern body </I>...?}<BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
The <B>switch</B> command matches its <I>string</I> argument against each of
the <I>pattern</I> arguments in order.
As soon as it finds a <I>pattern</I> that matches <I>string</I> it
evaluates the following <I>body</I> argument by passing it recursively
to the Tcl interpreter and returns the result of that evaluation.
If the last <I>pattern</I> argument is <B>default</B> then it matches
anything.
If no <I>pattern</I> argument
