I think we are confusing two kinds of storage here: virtual storage (which is
what is involved in the statements above, and real storage (which is what you
mean in the statement below).

Since GCI programs tend to be re-used the danger of "exhausting RAM"
is perhaps less. Why can't you just DEACTIVATE the GCI job when it is
done? Warning: I don't know your programs so I don't really know what
I'm talking about. Somebody else might give better advice. In any case,
"I'm not responsible for advice not taken".
