Very True! Before issueing 'Z' in =3.4 or 'C' in =3.1, you can use ISRDDN to see if you have SYSUT3/4 allocated or not. If it is indeed pre-allocated in TSO logon proc, they will be used. If not pre-allocated, the background services (PDF interface utility) will allocate them. In my case, SYSUT3/4 are not pre-allocated in my TSO logon proc, but are allocated, used during compress and then freed. To the OP: I see an interesting sample which can be useful to prevent gray hairs :-D during a compress: ISP.SISPSAMP(ISRCMPEX) - This sample will prevent compressing any SYS1. datasets. I also see you can use COMPRESS_UTILITY_PROGRAM_EXIT or COMPRESS_UTILITY_CLIST_EXIT. With them you can write something to do a backup automagically before continue to do a compress. Or you can selectively prevent compress at all. Thanks Shmuel for your kind post.
