JES3 OSE modification exit

The sample library member EQQUX191 contains the assembler source code of a JES3 OSE modification exit, IATUX19. Tivoli Workload Scheduler for z/OS uses events generated from the exit to detect output group purge.

If you are already using an IATUX19, you should include the code in your existing exit and reassemble.

Note:

If you are using JES3 Exit IATUX72 then this exit must return with R15 = 8 to call IATUX19.
