(RPG) An IBM programming language developed by Wilf Hey at IBM in 1965 for easy production of sophisticated large system reports.
RPG is a 3GL similar to COBOL, but more concise and supposedly easier for non-programmers to use. It processes its input one line at a time and does not treat tables as conceptual entities.
It was popular on System 34/36 minicomputers.
Versions: RPG II, RPG III, RPG/400 for IBM AS/400. MS-DOS versions by California Software and Lattice. Unix version by Unibol. Cross-platform version by J & C Migrations runs on MS-DOS, Windows, AIX, HP-UX, and OS/390.
