RPG is a high-level programming language (HLL) for business applications. Originally the initials stood for Report Program Generator, but currently it is referred to only as "RPG". IBM is the creator and primary vendor of RPG, but the language is available from other mainframe and microcomputer manufacturers, including Unisys. The latest version of RPG is RPG IV (aka ILE RPG) on IBM's Power i servers; it inherits the System i Integrated Language Environment’s features such as prototyped functions and procedures, static and dynamic binding, access to C routine libraries, dynamic link libraries, and fully recursive and re-entrant modular code.
There used to be a really bad looking mmorpg called Blademistress. I played it around 4 years ago. I had a swordsmith level of 5000. That is the highest I can recall off hand. I might even have some screenshots hiding somewhere.
