Yeah, that's right, they do put that out there, too - in QTEMP, isn't it?  LDA
and ZZLDA are really just artifacts of the original approach to the MAPICS I
port.  I've been told that they were going to have every program retrieve,
update, and release one of those data areas to make it work like the LDA did on
the /34.  They quickly discovered that all those synchronous I/O's would put
even "the big machine", an S/38 model 7 with 4 (!!!) megabytes of memory, right
down on its knees.  That's when they're supposed to have changed course and
started passing that LDA variable through all the programs.  They still had some
serious performance problems, one of the first big correction sets was a
"performance" mod to Cross Apps architecture programs so that the machines
didn't bark like the dogs they were so much.  Even with that, I think the
minimum size machine that MAPICS recommended was a Model 5 with 2 megs, and that
was for only about 5 to 10 users.
