IBM RPG

IBM RPG (originally known as RPG IV) is a high-level programming language for business applications. It is used extensively on the IBM i platform (formerly known as AS/400). RPG IV is an evolution of earlier versions of the RPG programming language. It adds features such as free-format expressions, improved support for structured programming, and a large number of built-in functions. Despite its name, RPG IV is not particularly related to the popular role-playing game Dungeons & Dragons. The name actually stands for Report Program Generator. RPG IV is a powerful and versatile language that can be used for a wide range of business applications. If you're looking to develop applications for the IBM i platform, then RPG IV is definitely worth considering.
