HyperAct, Inc. announces the availabilty of Parser/TP Version 3.0.

Parser/TP is a recursive decent expression parser package for TP, BP, BPW,
C++, Visual Basic and other systems that support DLLs.

This library includes the 5 basic math. operators (+ - * / ^), some basic
mathematical functions (sin, exp, cos, ln, log10, log2, abs, arctan, sqr, 
round, sqrt, tan, cotan, arcsin, arccos, trunc) and 2 constants (pi, e). 

Parser can be used to receive formula input from the user, and perform the 
necessary calculations during program runtime. 

Parser/TP supports a dynamic symbol table, that is created and maintained 
during the parser's execution. New variables are created when they are 
referenced for the first time, and receive the initial value of 0.0 . 

Variables values can be set by using the = operator  (e.g. myvar =
sin(anotherVar)*35 ), and used in user formulas.

This is an update to the package that was featured in the Aug. 94 issue of
the Windows/Dos Developer's Journal.

The package includes dos and windows demos.

Parser/TP is available as a shareware package, registration price is $40.

Evaluation copies can be found on garbo, simtel and cica.
