Well, if they want to use a chainsaw to open a bag of peanuts, you could write a JES exit, but the proper way to handle it is for the process that creates the JCL to generate a unique name. If they're using ISPF it's super easy to do it with File Tailoring, and many production control programs have similar capabilities.

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?
