Questions tagged [rpg]

DO NOT use this tag for Role Playing Games!! RPG (Report Program Generator) is a high-level programming language (HLL) for business applications. IBM is the creator and primary vendor of RPG, but the language is available from other mainframe and microcomputer manufacturers, including Unisys. Use this tag for older non-ILE versions of RPG from IBM and for non-IBM variants of the language.

What's the difference between EVAL and MOVE in RPGLE
