<h2>COMMALISTS</h2>
A commalist is a list of items, usually delimited with commas. For example:
<pre>
Harry,Ron,Hermione
</pre>
<p>
Commalists allow a set of values to be manipulated as a unit, which is often
convenient. There are
<a href="condex.html">
conditional expression
</a>
operators and
<a href="functions.html">
functions
</a>
that can process commalists.<tt> </tt>
<p>
Commalists may be suitable when individual values are known to be small in size
(such as integer id numbers) and where it is known that there will not be a large
number of choices. The total length of a commalist is limited to 250 characters.<tt> </tt>
<p>
The separator character is comma by default. This cannot be "escaped" but it
may be changed to another character using the script directive
<a href="control.html">
#control listsep
</a>
.
