Now on to the TSO ALLOCATE command. HELP ALLOCATE says:
...
BLOCK('VALUE')/AVBLOCK('VALUE')/TRACKS/CYLINDERS
...
Doesn't this mean that BLOCK, AVBLOCK, TRACKS, and CYLINDERS
are mutually exclusive? Yet, when I try:
allocate dsorg(ps) recfm(f,b) lrecl(80) -
space(05000) avblock(10) tracks cylinders
specifying not just 2 but 3 conflicting options, I get:
IKJ56893I UTILITY DATA SET NOT ALLOCATED+
IGD17051I ALLOCATION FAILED FOR DATA SET
SYS09089.T110640.RA000.SPPG.R0103651
, PRIMARY SPACE EXCEEDS 65535 TRKS
***
... no failure on syntax.
BTW, isn't "65535 TRKS" pretty restrictive for some modern DASD?
