The OpenEdge Application Compiler utility lets you compile a set of source procedures (.p files) either for the duration of an OpenEdge session (or until OpenEdge runs out of directory entries) or for permanent storage. For a session, OpenEdge creates temporary r‑code files. For permanent storage, OpenEdge creates r‑code files that inherit the name of the source file and a .r extension by default. Once you compile a procedure, it does not get recompiled when you run it, so the procedure runs quickly. For more information on r‑code, see OpenEdge Getting Started: ABL Essentials.
