Mike,
Why bother about creating different members based on the size of the file?
Most of the parms that Billy is overriding are good candidates for Installation
defaults. All they need to do is change 1 member and e
e questions, but other folks may still jump in, I guess.

If you want to force HIPERSORT, then you need to turn off other paths of code.
Ok, thanks, Kolusu. Unless there would be a compelling reason to redirect the
SORT a different way, I will let the program determine the best way to go. So
far, it sounds like each of these memory paths will produce somewhat similar
stats to other paths, and I would not want to ask my client try

MEMLIMIT and REGION are decent enough, size-wise, but DFSORT doesn't seem to
