I have uploaded to SIMTEL20: pd1:<msdos.turbopas> PARSE10.ZIP Expression parser for Turbo Pascal Parser is a recursive decent expression parser unit for Turbo-Pascal, this unit includes the 5 basic math. operators (+ - * / ^), and some basic mathematical functions (sin, exp, cos, ln, log10, log2, abs, arctan, sqr, sqrt, tan, cotan, arcsin, arccos) and 2 constants (pi, e). Parser can be used to receive formula input from the user, and perform the neccessary calculations during program runtime. Parser supports 10 general purpose variables (v0, v1, .., v9) that can be set (using the = operator) and used in formulas by the user.
