<p>The Clear Message Queue (CLRMSGQ) command clears (removes) all messages from a specified message queue. Once cleared, the data can no longer be displayed or printed. If the specified message queue is not allocated to a job, it is implicitly allocated by this command for the duration of the command. If the specified message queue is *WRKSTN or a work station message queue, it is not allocated and the message queue is cleared even if the work station device description is allocated to another job.

</p>
|
||
|
|
<p><b>Restriction:</b> You must have change (*CHANGE) authority to the message queue and use (*USE) authority to the library where the message queue is stored.
