PURGE={YES | NO}

This parameter defines the action to be taken when a request times out. This parameter is used only when the WAIT =YES and TIMEOUT parameters are also specified.

If PURGE=YES is specified, a request will be purged from the queue when the TIMEOUT interval expires before the request is completed. If PURGE=NO is specified (or defaulted to), the request will not be purged from the queue when the TIMEOUT interval expires. Either way, a return code will notify you that a request times out.
