3-468: The Integrated Language Environment (ILE) is a programming model developed by IBM for their AS/400 line of computers and remains an important part of the IBM i programming environment. IBM provides ILE compilers for C , C++ , RPG , COBOL and CL . For RPG, COBOL and CL, there are both OPM compilers (still sometimes used for legacy applications) and the new ILE compilers. Likewise, as well as ILE C, there
6-740: The introduction of ILE. It provided a common interface among the disparate programming languages available to the AS/400 computer platform. ILE was an improvement on the two existing programming models available on OS/400 – the Original Program Model (OPM), which was used for traditional business programming languages such as RPG and COBOL; and the Extended Programming Model (EPM), which was introduced for use by C and Pascal. OS/400 (now IBM i) continues to support OPM and EPM to run legacy applications, but new development
9-453: Was an earlier EPM-based C/400, although that has been discontinued. Pascal and FORTRAN compilers were made available for EPM, but ILE compilers for those languages have never been released; likewise, BASIC and PL/1 compilers were available for OPM, but ILE compilers have never been released for those languages either. On February 16, 1993 IBM announced that V2R3 of OS/400 would include major changes to its programming language support –
