The JCL manual says exactly that.
Great. Thanks to all for your help.

Hello Willie -
Yes indeed it does
Not the maximum but the actual number of blocks that will be allocated.
Without some CBT type add-ons, the directory will neither shrink nor grow.

At the risk of being obnoxious, why didn't you check the JCL manual, before
asking the list?

Ed,
Apples and oranges. CLPA is used once a month (or less) during scheduled
outages and the last time I checked CPU utilization on the CPC was
pretty
OTOH, IEBCOPY gets executed thousands a times a day. Including prime shift /
hours where CPU utilization is at or near 100% across all our
CPCs.
Not at our shop.
And, not all IEBCOPY's are load libraries.

If there is a difference in provessing it would be because copymod does
a re-link-edit of the modules as opposed to a straight copy.

Its funny that you should mention the ISPF issue. A few years ago
someone at our site (I won't name names) used p;3;3 to copy the LINKLIB.
There is now an option on the copy screen to Process member aliases

z9 cycles don't come cheap.
But, optimising a few batch copies doesn't save much of that.

use COPYMOD if you like waiting longer. But I would never suggest it be done

Possibly, but I spend the time in the areas that make a difference.
