JES3 OSE modification exit
The sample library member EQQUX191 contains the assembler source code of a JES3 OSE modification exit, IATUX19. HCL Workload Automation for Z 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.
