<p>The Trace commands such as STRCMNTRC, STRTRC, TRCINT and TRCCNN have the
|
||
|
|
capability to watch for a specific event and end the trace when this event
|
||
|
|
occurs. An event can be a message being sent to a specific message queue,
|
||
|
|
history log, job log, or LIClog. If specified in the TRCPGM parameter, the
|
||
|
|
watch for trace event facility will call a user-written program in the cicumstances

specified in the Trace option setting parameter.</p>
