HASPJQS calls your exit routine with the address of the JQE that represents the job selected by the $QGET routine. Your exit routine has opportunity to examine this JQE and return to JES2 with the indication to select it for further processing or reject it.

HASPXEQ also calls exit 49 when processing the $S Job command. The exit is called once when the command is issued, under the HASPCOMM PCE while processing the $S Job command. If a job is rejected at this point, a message will be returned to the operator that the job cannot be processed. The second point the exit gets control is when the job is selected for execution under the execution PCE on the member where the job will execute. If a job is rejected at this point, a message is issued to the console that the requested job is not found.
