I need some help from the P21 assembly language gurus! I'm working on a C
compiler for P21. To save myself some work, I'd like to use some words
from P21Forth as a runtime library. That is, I'd like to "call" words
from outside the normal Forth inner interpreter. What I have so far is
appended below. This looks kind of clumsy. Is there a better way? Thanks!
