Thanks for the replies regarding the mysterious memory loss.  As for the
concerns about having LAST STACK and LAST ARG turned on, turning them off made
no difference.  I thought the 48 just stored a copy of the pointers to an
object (instead of storing a copy of the object) until you modified one of the
copies.  There should have been enough memory to put a copy of my 7K object on
the stack for use by my program.  (BTW, before someone asks, I didn't have
anything on the stack before I ran the program.)

The one thing I didn't try was turning off LAST CMD, but I thought this only
repeated the last operation.  What exactly gets saved?

I'm still convinced the calculator lost track of the memory because the program
works fine now, even with LAST * turned on.  (It also worked fine up until I
got the "Insufficient Memory" error.)
