If you are not allowed to fix the JCL, JES2 exit 6 certainly sounds like a reasonable way to go, as long as it isn't the camel's nose under the tent. Good luck.

Jes Exit 6 seems to be the best place to do this. There is only a max of one dataset per job and it's never re-read in that same job (or any other) and we already know what the dataset(s) are called, so it's pretty simple to scan for the DSN= text object and if the supplied DSN matches one of the ones we want, we just replace it with the symbolic. Actually at that point in time I could just insert the actual date and time. The test version does just that. Of course as soon as I started writing the exit, several people came in to ask for more "features". The only thing I forgot was a way to bypass the exit in the event that I wanted to actually process one of the tapes manually (by volser), but I now have that worked out as well, I just don't have time to test it properly at this time. I also think it's possible to limit the processing to ONLY the jobs that we know will contain the fiche tapes, so I'm waiting on a programmer to tell me if that's true.

Actually I'm leaning towards the JES or SMF UJI exit as well. File tailoring doesn't help in this case because most of the JCL doesn't get submitted via TSO.

If they're using ISPF it's super easy to do it with File Tailoring, and many production control programs have similar capabilities. -- Shmuel (Seymour J.)

Hi, I was asked a question today that I honestly don't know how to answer. The programmer has a (very large) series of jobs that generate fiche tapes that get created and have a expiration date but never are cataloged (because they all have exactly the same DSN). So over time, they ended up with about 30,000 tapes from the over 9,000 jobs that CA-1 keeps around until expiration date. Obviously, these are not the easiest datasets to use later because they need to look up the tape volser every time. The problem is that they want to know if there is a way to automatically catalog datasets at creation time, to which I told them we could, but only 1 of them because you can't catalog two datasets with the same name. But they want to have "the system" which I'm guessing is me :), dynamically rename these datasets at creation time to add a date and time, such as change HLQ.FICHE.TAPE to which I would dynamically make it HLQ.FICHE.TAPE.D091720.T1123, meaning today's date and the current time (if it was 11:23am). I can't think of a way to do that in an acs routine, or any other simple way, and I'm hoping that someone has an idea that might apply here. I think I can alter almost anything about the dataset, except the name. Is there something I am missing?
