Yes, I *was* being too vague. In this case, an RPG Cycle program that updates records in one file based on corresponding records in two other files. It can be re-run any arbitrary number of times, and is 100% idempotent for target records for which the source records are unchanged from the previous run (which would likely be the overwhelming majority of the target records).
