<h1 class="topictitle1">Monitor for notify messages</h1>
|
||
|
|
<div><p>You can monitor for notify messages that are sent to your CL procedure's
|
||
|
|
or program's call message queue by the commands in your procedure or program
|
||
|
|
or by the programs and procedures it calls. </p>
|
||
|
|
<div class="section"> <p>Notify messages are sent to tell your procedure or program of
|
||
|
|
a condition that is not typically an error. By monitoring for notify messages,
|
||
|
|
you can specify an action different from what you would specify if the condition
|
||
|
|
had not been detected. Very few IBM-supplied commands send notify messages.</p>
|
||
|
|
<p>Monitoring
|
||
|
|
for and handling notify messages is similar to monitoring for and handling
|
||
|
|
escape messages. The difference is in what happens if you do not monitor
|
||
|
|
for and handle notify messages. Notify messages are also percolated from
|
||
|
|
procedure to procedure within the boundary of the activation group. If the
|
||
|
|
activation group boundary is reached without a <span class="cmdname">Monitor Message (MONMSG)</span> command
|
||
|
|
being found for it, the default reply is automatically returned to the sender
|
||
|
|
of the notify message and the sender is allowed to continue processing. Unlike
|
||
|
|
escape messages, unmonitored notify messages are not considered an indication
|
||
|
|
of an error in your procedure or program.</p>
