Hi
Thank you, it is exactly the problem .
The dataset not opened in the job step at all.
But in DASD the new generation exists, so if someone opens the actual
new generation, he will get an empty disk dataset, but for TAPE he will
get the last nonempty one.
If you know this, it is o.k, if not and you change from DISK to TAPE you
will get a surprise.

If I understand you correctly, you're saying that the +1 generation gets catalogued if on a disk, but not if
on a tape. In a disk SMS environment, the creating of a disk dataset and cataloging thereof causes no problem
because SMS usually "initializes" the dataset with an end-of-file. In the case of a tape dataset,
the dataset is "initialized" only if an OPEN is done on it. I don't know how it is done, but z/OS
does not catalog a tape dataset which was not OPEN'ed. The "solution" is to OPEN the tape dataset.
If you can't do it in any other way, you could always use IEBGENER to copy a DD DUMMY (0 records) to the
tape. Either with DISP=(NEW,CATLG) on a step before the current step, changing the current step to
DISP=(MOD,CATLG). Or on a subsequent step with DISP=(MOD,CATLG). At least, this is how I do it.
