That's very helpful, especially the GitHub link for the source code. I'll share that with him. I also agree with Ralf that FORTRAN77 is not the right programming language for what this person is trying to do. They're writing a little address book app -- that's much easier in a language like C or C++. But I think this person is just excited to try retro-programming in FORTRAN, so "doing it for the challenge" probably overrides "best language for the job" in this case. :-) >
