I honestly don't think there was a default as the region it ran in I
"think" was 256K. Giving it plenty of memory on the parm really did
help out. I know my SMPE runs ran faster than any elses in the group.
I also set up a larger size (4096K,1024K) on the link/binder runs and
SMPE just ran terrifically (reasonably) fast. Yes and I always ran
with a 6M on the job card (nothing on the exec). I vaguely remember
bumping up the second size on the link did not help at all. I think I
read an APAR on the link editor that explained this, but again this
was ages ago and since it worked I was not about to complain.
I remember also that if you gave IEBCOPY enough memory it didn't need
sysut3 and 4

they were pds's).
Would that have been bigger or smaller than the default? (He asks,

4,000,000K rattling around in his jeans pocket.)
