The RPG programming language originally was created by IBM for their 1401 systems. IBM later produced implementations for the 7070/72/74 [4] [5] and System/360; [6] RPG II became the primary programming language for their midrange computer product line, (the System/3, System/32, System/34, System/38, System/36 and AS/400).
RPG II is a very early and popular version of the IBM RPG programming language. It was developed in the late 1960s and designed to work on the smallest IBM systems of the time such as the IBM 1130 , IBM System/3 , System/32 , System/34 , System/36 .
RPG III is a dialect of the RPG programming language that was first announced with the IBM System/38 in 1978. An upgraded version, RPG IV, was introduced in 1994. In 2001 RPG was again updated to remove a number of column restrictions. RPG continues to be upgraded on a regular basis. [1] The last fixed form restrictions were removed in 2015. [2]
ibm rpg ii The IBM System/3 was an IBM midrange computer introduced in 1969, [ 1 ] and marketed until 1985. It was produced by IBM Rochester in Minnesota as a low-end business computer [ 2 ] aimed at smaller organizations that still used IBM 1400 series computers or unit record equipment .

The IBM System/32 [1] [2] (IBM 5320) introduced in January 1975 [3] was a midrange computer with built-in display screen, disk drives, printer, and database report software. It was used primarily by small to midsize businesses for accounting applications. RPG II was the primary programming language for the machine. [4]
The IBM System/36 (often abbreviated as S/36) was a midrange computer marketed by IBM from 1983 to 2000 - a multi-user, multi-tasking successor to the System/34. Like the System/34 and the older System/32 , the System/36 was primarily programmed in the RPG II language.
IBM provides ILE compilers for C, C++, RPG, COBOL and CL. [1] For RPG, COBOL and CL, there are both OPM compilers (still sometimes used for legacy applications) and the new ILE compilers. Likewise, as well as ILE C, there was an earlier EPM-based C/400, although that has been discontinued.
