...That can be Used by C, VB or other Applications.
I have been programming in VB for a number of years and have been tempted to write some of my code using C into a DLL for a couple of reasons:
Unfortunately C seemed to be too hard and I never had the time, or courage, to try. When Delphi came along I thought this could be a solution to my dilemma. However the only Pascal I did was 15 years ago, so I had to go back to basics.

I am sure there are Pascal gurus who could improve my code and I encourage you to participate in this discussion.
