Hi Fred,
This might occur because:
- Your shop has a storage software product (e.g. Mainview SRM) which
adjusts allocations automatically.
- Your shop has ALLOCATION Exits (The ISPF Allocation Exit is the not
the same as the TSO/Batch Allocation Exit).
Regards,
David

Hello,
I have a user that is allocating a data set in TSO and REXX using the following
command
ALLOC DA('ABCD.EFG') NEW CATALOG UNIT(SYSALLDA) DSNTYPE(LIBRARY) LRECL(121)
RECFM(F B A) CYL SPACE(9) BLOCK(27951) DIR(100)
The data set is allocated, but the unused space is released, so the data set is
only 6 tracks.
I allocate the same data set in ISPF 3.2 and the data set is allocated with 9
cylinders.
The same SMS management class and data class is assigned for both allocations.
Is it possible not to release unused space when using the TSO ALLOC command?
