To answer your question first, I personally don't know of anything that can convert program code to C#. Even if you DID find something to do that, it would not help you if you did not understand C# well enough to interpret that code.

I suggest you start by trying out small C# programs, perhaps from a starter book, and develop them from there. The more you learn, the more you will be able to accomplish, and the more you accomplish, the more you will GLOW.

Start out with a "guess my number" game. Have the computer pick a random number, and see how many tries it will take for you to guess it.
There are tons of examples of code on the web, too.
If you have SPECIFIC questions, come on back.
Cheers!

The problem is that GWBasic and Cobol are very different languages to the C family of languages (C#, Java, etc). You basically need to look at the code, work out where the subroutines are, and whether any special features of the language are being used.

For instance, in cobol, you could code
In C#, this would have to be split into 2 routines, one calling the other. Also, everything in working storage is a global variable. You need to take the program apart and re-assemble it when doing a gwbasic/cobol conversion to C#. You need to watch out for the tricks used in the language like COBOL's move corresponding. No other language has that feature.

if you ever saw the commenting assembler that was sold by V-communications, you would understand what I mean. The comment was really impressive smart.
