Small suggested edit: For the second reference to variable 'A' in the expression

L(MM:M+12xA-2)

Change the direct reference of variable 'A' to G(A)

L(MM:M+12xG(A)-2)

so that the variable 'A' does not appear in the menu.

Very neat program! Someday I hope I'll master this programming language. Makes obfuscated C look like child's play
