Q: I need to call some C routines from RPG. At one time, IBM's Barbara Morris had written a guide to help people figure out how to do that, but the site appears to be down. Is there another place I can get her guide?

A: The guide is called "Converting from C prototypes to RPG prototypes" and is aimed at RPG programmers who need to call routines written in C. The guide explains how C prototypes work and offers advice for converting C prototypes to their RPG equivalents. For many years, Barbara made the guide available through opensource400.org's website. That site has been unavailable for a while, however.

Recently, I caught up with Barbara Morris, and she agreed to let me post the guide on my own website so that everyone can take advantage of the document. You'll find it here:
