- Leonard's explanation is complete and accurate. I thought I would
- just add a bit of a historical note.
-
- My best recollection is that there was a time when esoteric names
- were cataloged "funny" even when the cataloging was DISP=(,CATLG)
- from JCL. Note that the "funny" cataloging applies equally to
- tape and disk data sets, and lots of shops use esoteric tape names
- to direct tape mounts to pools of tape drives.
-
- I think the cataloging for JCL was fixed either in the last few
- releases of MVT or in the first few releases of MVS. In any case,
- it was a long time ago.
-
- Prior to the fix, most systems programmers were well aware of this
- quirk. Since the cataloging was "wrong" for esoteric names, even when
- the cataloging was done from JCL, you could not help but have many
- "incorrectly" cataloged data sets if you supported esoteric names at
- all. Furthermore, in this type of environment it was not reasonable
- to declare user error and put the onus of fixing it back on the users.
- It didn't have to be fixed unless you did a sysgen, but then fixing it
- was critical. By hook or by crook (or by handy dandy utility program
- that you wrote at 3:00 in the morning), you had to recatalog a lot
- of data sets.
