Assuming a keyed PF, non-uniquely keyed, opened as externally-described, from RPG:
Is there any guarantee that, when reading all the records for a particular key (starting with a CHAIN for the initial read, and a READE in a loop for subsequent reads), they'll show up in order of ascending RRN within those matching the key?
