> Bob, are you sure this is true for all PICs ? (esp 12 and 14 bit cores) ?

The description of the stack in all uChip documentation I have seen is the
same: push throws the oldest entry into never-never, pop duplicates the
oldest entry. Hence the number of entries always stays the same. Note that
this is not exactly the same as a cyclic stack, but I'm not sure you can
make a program that depends on the difference.
