There were several dialects or versions of RPG over the years: IBM created
RPG for the System/360 (1964), RPG-II for the System/3 (1965), RPG-III,
RPG/400 for the AS/400, RPG-IV, and Visual Age for RPG. Other companies
produced versions of RPG-II and RPG/400 for MS-DOS and Windows operating
systems.
