Actually, while this is undoubtably true, for all practical intents and purposes there is no JCL as we know it behind these 'address spaces with a number', even if they're considered 'STC' ny z/OS. You will need the D OMVS and F BPXOINIT commands to 'see' the connection (via asid) between the jobname and what USS cares about, the pid. And with the pid goes 'a command'. My favourite hate-application has about 65 address spaces, all with the same 'jobname' (other than the number for the fork()ed things) and the same userid. That's why they are so hard to control for an old-time z/OS sysprog. >3) Do/can USS processes run under JES control? (I assume not as we have >sometimes two or three processes with the same name which is a no-no in Z) As was stated before, the same jobname is NOT a no-no anymore. That restriction was lifted sometime in the nineties, for USS to work. I have a dim recollection that you could also run batch jobs with the same name simultaneously if some sort of parm is set *somewhere* (no clue where).
