Thanks again Tony, and I tend to agree that going the storage route in this
case is a dead end.
I've been trying to avoid command/response when possible for a few reasons:
- Command response timeouts (a storage call when possible should be
immediate)
- Key message ID avoidance ("D TS" result was updated from IEE114I to
CNZ4105I in z/OS 2.3)
- Log noise ("D TS" produces a 3 line MLWTO)
- Extra/Undesired information returned (I'm interested explicitly in
USERMAX value)
If I can "quietly" get the exact information desired with less overhead, I
feel like I improved my world in a little way :-)
... and if I can't, that's ok too.
