<ul>
<li>
<p>
<tt>collect ()</tt> <br>
causes a garbage collection to occur.
</p>
</li>
<li class="gap">
<p>
<tt>pack ()</tt> <br>
shrinks the heap as much as possible so that other processes can use available RAM.
</p>
</li>
<li class="gap">
<p>
<tt>setMessages b</tt> <br>
controls whether diagnostic messages are printed at the beginning and end of each garbage collection. It is the same as the <tt>gc-messages</tt> runtime system option.

</li>
<li class="gap">
<p>
<tt>setSummary b</tt> <br>
controls whether a summary of garbage collection statistics is printed upon termination of the program. It is the same as the <tt>gc-summary</tt> runtime system option.

<li class="gap">
<p>
<tt>unpack ()</tt> <br>
resizes a packed heap to the size desired by the runtime.

<tt>Statistics.bytesAllocated ()</tt> <br>
returns bytes allocated (as of the most recent garbage collection).

returns bytes live (as of the most recent garbage collection).
