I have accepted the challange of documenting three versions of the same process. We call it the "Calc Engine" and it exists in 3 flavors. One is in PRGs, another a non-visible class and yet another is contained in various methods on a form. It is fairly complex. The three are basically the same, but over the years differences have crept in. We want to only have 1 (likely a class) in the end. I was wondering what everyone thought was the best way to compare/document them to accomplish this? Thanks!
