RPG IV

RPG IV is the latest syntax of the RPG (Report Program Generator) high level language, the primary programming language on the System i. RPG was designed for writing application programs for business data processing requirements.

RPG IV is also commonly, but incorrectly, called ILE. The Integrated Language Environment (ILE) is a runtime environment for the i5/OS operating system. ILE concepts apply not only to RPG IV, but also to the other ILE languages: CL , COBOL, C and C++. The IBM program product that compiles RPG IV code is called ILE RPG/400; hence the confusion.
