Multilevel returns
Bob Ammerman [rammerman at prodigy.net] of RAm Systems says
The PIC18Cxx2 chips contain quite a few nice new features. One of the neatest
is programmable access to the stack. This feature allows many powerful tricks.
Notes:
-
this code has _NOT_ been tested!
-
all multi-byte values are little-endian
-
I assume the code space never exceeds 16 bits worth (which it never will
on the 242, 252, 442 or 452 chips).
