The problem I have with COND= is that it's back-asswards. First, it

I attach a discussion about the IF/THEN vs COND= we had in 2011.
That COND= BTW was for a real case of a chemical company running its
payroll 100+ step job on our mainframe, but with a COND=(4,LT) on its
job card. Each time one of its jobsteps hit a CC GT 4, the job ended and

Mike,
IMHO you talk about EAV in DS8000, but not about EAV.
EAV Volume (*) can be up to ~1TB big, but chunk size of 1113 cylinders
is for DS8000 family, AFAIK.
Space above 65520 cyl. is called EAS and from z/OS point of view the
smallest chunk is 21 cylinders.
So, you can allocate 1 track data
Volumes have gotten bigger. The first 64K Cylinders (Mod 54) remain
the same, but EAV space past that can be added in 1113 cylinder chunks
to a multipile of 1113 cylinders. 250GB first step then 1000GB (or
so).

We love our 24-bit addressing and avoid 31-bit or 64-bit.
OK, there were some changes:
We migrated our memory from core to TTL.
Our Bus&Tag channels rusted away, so we moved to fiber optic.
