I observed an abend S237-04, when reading dataset from tape (using
IEBGENER).
The manual says it is due to discrepancy between # of blocks read and
the value written to EOF label.
As a matter of curiosity, was the tape ever processed DISP=MOD?
AFAIK no. 99.9% sure.
Was the tape written by a tape-to-tape copy utility?
No.
Was it exported from a VTS?
No. It is physical tape. 3592-J1A with ETC cart.
As I mentioned before, it is probably not a media error, because the
tape can be read using BLP. It is single-file tape, so I can read three
"BLP datasets": label, dataset, label.
BTW: I noticed, that I have UHL1 label. In fact I never had to do with
user labels - AFAIK it is processed by application-delivered routines.
Is it a point of interest ?
Hint: no user labels at EOF, only header.
