Did you pull some things from the AEC rom or is this a new masterpiece of your own devising ? :-)

Entirely new code, nothing from the AECROM which did the FOCAL self-programming, not the formula interpretation like ours do.

It's all new ideas, Greg's design of a "symbolic buffer" where the intermediate steps (values, functions and status) are pushed to and popped from as required according to the syntax. A beauty to see in action ;-)
