- I can add only that most shops avoided this problem by *NEVER* altering
- the order of the defined esoteric names. If DISK was the third name
- and TAPE the fourth, there they remained. Forever. (Talk about stable
- SYSGEN decks.) And the scenario Jerry Bryan describes is the reason.
- Keep in mind that this was before TSO (and even before Wylbur); most
- shops had only card readers, and to recatalog many data sets was, well,
- nearly impossible.
-
- I don't remember that DISP=(...,CATLG) used esoteric names, so that
- must have been fixed by MVT release 16 or so, if not much earlier...
