Coding in RPG (Report Program Generator) has been taking place since 1959. Of course, the language has changed dramatcially over the last half century. (Click here for a PDF for an Intro to RPG.) It has had to, in order to keep up with the changing demands placed on midrange computer systems. From IBM S/3, to S/34, through the S/38 and S/36 years, and through the AS/400, iSeries machines, and now the Power i products, RPG has been the overwhelming language of choice for application development on the IBM midrange platform.

The language began as a fixed-format columnar code for report writing and has morphed into a free-format language of tremendous scope. As of Release 7.1 of the i OS, ( new operations after TR7), RPG is no longer framed by fixed-format instructions, or definitions.
