RPG history

RPG was originally developed in 1959 as the Report Program Generator' and was then a utility that replaced some of the punched card processing on the IBM 1401, RPG II was introduced for the IBM System/3 in the mid/late 1960s and had by that time started to resemble a programming language more. RPG IV was introduced on OS/2 and AS/400 in 1995
