/*Now, we'll use the data heap glbl option
to force global vars onto the data heap.
You can turn the data heap flag
on and off within your programs, leaving
ones which need initialization on the code heap.
You can't dynamically initialize data heap
glbls--they are consts.This might be a silly
point, but might res in odd differences, perhaps
from the order things are evaluated.
Data heap glbls are good for AOT modules
because they don't take-up room in the .BIN.Z file.
