RPG also stands for role-playing game.
RPG (Report Program Generator) is a programming language that originated as a report-building program used in DEC and IBM minicomputer operating systems and evolved into a fully procedural programming language. Its latest version, VisualAge RPG, is supported by IBM's leading minicomputer system, the AS/400. Historically, RPG has probably been the second most used programming language, after COBOL, for commercial applications on mid-range computers.
