| − | '''RPG''', which stands for ''Report Program Generator'', is an easy to learn and understand programming language that is well suited for developing business applications.

| − | [[RPG]] is available only on [[IBM Midrange]] platforms, this is because the technology has evolved over many years to leverage operating system resources. A comparison between [[RPG]] and [[Java]] can be made so long as [[Java]] is used in a developer framework or one of the available [[application servers]]. Unlike Java, however [[RPG]] contains language-level features for common business tasks such as database access. Also the operating system contains extensive support for debugging and run-time identification of [[RPG]] code. The main perceived flaw with RPG is that it is not object oriented, nor does it contain direct support for [[GUI]] Graphical User Interface. There is a large established base of [[RPG]] code in production environments, usually performing heavy-lifting batch-oriented data tasks, or providing support for interactive [[ERP]] applications, either with native [[5250]] interface or with a [[GUI]] or Web [[Skin]] applied over the [[5250]] data stream.
