I've been given the task of rewriting a small portion of our large COBOL system in VB.NET. The code that I'm rewriting happens to call a subroutine that makes massive calculations. I'd prefer not to have to rewrite that entire subroutine as well. I have the subroutine's .cbl file, as well as an EXE and an associated DLL. I know from the code I'm rewriting and the sub's .cbl file what input and output parameters I need, but I have no idea how to pass/receive them. I know almost no COBOL and have a boss who thinks this should be the easiest task in the world. Please help me.
