Thanks for pointing to this archive. Here are some comments on the programs contained in it and their compatibility with FB and FBMath:

* calc.zip : Calculator - portable to FB?

* CubicEquation.zip : FBMath allows complex roots and higher degrees.

* LinearSolver.zip : Gauss-Jordan method is already in FBMath. Polynomial regression is planned (I have already working codes in QB and VB, but I have to improve the graphics).

* rq_math.zip : most functions for real variables are already in FBMath. Complex functions will be added soon.

* simplex.zip : simplex method for linear programming. This one should be interesting to port to FB (FBMath has already the simplex method for NONlinear optimization, because I use it in my work ;-))

* TrigSolver.zip : may be interesting to port to FB, too.

The other programs are parsers. Since several parsers have already been implemented in FB, it seems wiser to use them.
