You mean stack usage - yes? Under stack frame, I understand the formal layout,
not the size (but I might be wrong).

Is it really a problem with todays tyoical computers, to use much stack? I
remember DOS and Atari days, where this was an issue. Since I started using DOS
extenders, the issue was gone for me. At least it seems so. Is there some
unusual penalty still, for using much stack space? Of course, I am aware of
caching issues, etc. Even of more subtle things, that references to local vars
might need offsets >= 127 will need longer code. But to me, this seems all more
or less negligible.

BTW. I always thought, you had another live as some famous math professor.

Cheers,
Dieter
