Actually, I wasn't talking about the linkage stack at all. I was referring to
software-only stacking.
Ah, my mis-understanding.
In the early days, people rarely coded hierarchically. Everything was a flat
programming model, one routine following another with (one or more) branches to
the label of the next routine. These days, people understand the value of nested
logic. A software register stack is practically a necessity for such coding.
Totally agree with all of the above.
I have made a simple stacking macro available publicly to help those who might
be challenged to 'roll' their own. More sophisticated stack services (such as
the one we use internally) handle so-called 'automatic' variables as well.
Excellent. One can also use the CEEENTRY macro to
handle automatic variables (although it does have
some shortcomings, such as using non-relative branching
instructions).
