I have a program that was written in C for Windows, it compiles to a DOS executable. It consists of a number of mathematical equations that determines Magnetic Declination. It reads data from a text file. I would like to have this C program converted over to a FB function. The C code looks pretty simple, but the formation is Greek to me. I have a little $$ available to make this conversion. If you are interested please email, thank you! David Parrish dp@...
