- MVS/ESA 4.2 Config Program (GC28-1651) says: "if you use the old
- catalog, and it has esoteric names for datasets ... make no
- deletions, make additions only at the end". MVS/XA and below (we
- skipped version 3, so I have no doc on that) explicitly mention the
- master catalog here, which seems to imply that esoterics in
- usercatalogs are ok. They are not.
-
- But why do we have to invent the corrective tool ourselves? Why is
- there not an option (PARMLIB or so) that we can ask catalog
- management to automatically recatolog the dataset.
