<h2>Syntax</h2>

<h2>Description</h2>
<p>The 'gc' function starts a garbage collection of the unused memory of
XLISP. <a href="nil.htm">NIL</a> is always returned.</p>
<h2>Examples</h2>
<pre class="example">
(gc) <font color="#008844">; start a garbage collection right now</font>
</pre>
<p><b>Note:</b> The system will cause an automatic garbage collection if it
runs out of free memory.</p>
<p><b>Note:</b> When 'gc' is called or an automatic garbage collection
occurs, if the amount of free memory is still low after the garbage
collection, the system attempts to add more segments [an automatic
