<h3>Usage Notes</h3>
<ul>
<li>
<p>Any registered user-written condition handlers not unregistered by CEEHDLU,
are unregistered automatically by the system upon removal of the associated
call stack entry from the call stack.</p>
</li>
<li>
<p>If the specified procedure is registered more than once, the most recent
registration is removed. Earlier registrations remain in the queue for the call
stack entry.</p>
</li>
<li>
<p>The message CEE0257 occurs if the pointer contained in <em>procedure</em> is
not a procedure pointer.</p>
</li>
</ul>
