I read your more recent ply, but I'm curious about the history.
"Sent out" seems to imply they're physical tapes to go in a courier pouch.
I had imagined virtual. And RETPD must be comfortably beyond the
"someday they might be needed."
Does/did the process depend on the DSN's being precisely
hlq.FICHE.TAPE, perhaps to trigger an exit or operator
action?
I don't see that cataloguing unique DSNs would help much -- it leaves
the chore of associating DSN rather than VOL=SER with a particular
job to be retrieved. It would enable a DSLIST of all such tapes.
