AS400 / ISeries Programming resources & Utilities

IBM's midrange computer is known as AS400 or ISeries or I5. Compilers on AS400 are RPG/400 and RPG-IV. Cobol, C and Java are also available for the AS400 from IBM. SQL is available, either as a stand-alone query tool or embedded within the source programs.

ILE, put very simply, means that an executable program on AS400 can be built up from a number of compiled program modules. Thus an executable program can be built from RPG-IV modules only, or from modules written for a combination of compilers such as RPG-IV, C and Cobol. RPG/400 programs are not modular - each compiled RPG/400 is an stand-alone exsecutable program. RPG-IV is also known as ILE RPG.

This is a site for software developers working on IBM's ISeries (aka AS400). The aim is to build this site into a comprehensive knowledgebase for RPG/400 and RPG-IV on IBM's ISeries.
