Question 1: I see you got 3 extents. How many of the 7 volumes did that cover?
Two (2) mod-9's; RLSE released all the other requested space.

Question 2: what amount was allocated in the three extents?
94245tracks or 6283cylinders: see below
3.4 Data Set Information shows 6654 cylinders (cannot explain that)

Question 3: Any reason not to use an SMS pool? Yes; we are a Payroll Processing
center that pays 660,000 Federal Employees utilizing Computer Associates
IDMS. A lot of the code was written in the 1970's and 1980's;
more importantly a lot of the batch processes that are used
Un-catalogs DSNs which my understanding in SMS un-catalogs does
a delete which the programmer could not go back to a previous step where a
DSN was un-cataloged re-catalog the DSN and start processing from that
step.

I see you got 3 extents. How many of the 7 volumes did that cover? The VOLUME
SERIAL shows multiple volumes, but it is helpful to know how many were used.
next, what amount was allocated in the three extents? I would suspect that for
non sms the VOL= might need to include serial numbers it could go to.
Any reason not to use an SMS pool?
