I have been programming for a long time, I have learned every language I could get my hands on, all the majors and and a few minor ones. My favorite language is pascal, I really liked Borland's Turbo Pascal implementation, but now it is called Delphi, not quite the same, but still the best compiler out there.
Years ago, I wrote a pente game in Turbo Pascal, I then updated it to a win32 application using Delphi, I am releasing the source, if you find it useful, let me know, if you make any improvements, please send me a copy for inclusion.
More recently, I wrote a program to allow calculations of payments and an amortization schedule, the program can also reverse calculate interest or loan period.
