DOS Pascal Interop

1981 saw Pi establish itself as the place for serious DOS↔Pascal interoperability infrastructure. Dana Schwartz's HUFFIN (Pascal→DOS text, July/August 1981) and Dr. Wo's PUFFIN (DOS→Pascal text, September 1981) form a bidirectional bridge between Apple's two main operating environments.
