ILE RPG is an implementation of the RPG IV programming language in the Integrated Language Environment. It is one of the family of ILE compilers available on i5/OS.
ILE is a recent approach to programming on System i5. It is the result of major enhancements to the System i machine architecture and the IBM i operating system. The ILE family of compilers includes: ILE RPG, ILE C, ILE COBOL, ILE CL, and VisualAge for C++. Table 26 lists the programming languages supported by the IBM i operating system. In addition to the support for the ILE languages, support for the original program model (OPM) and extended program model (EPM) languages has been retained.
| Integrated Language Environment (ILE) | Original Program Model (OPM) | Extended Program Model (EPM) |
|---|---|---|
| C++ | BASIC (PRPQ) | FORTRAN |
| C | CL | PASCAL (PRPQ) |
| CL | COBOL | |
| COBOL | PL/I (PRPQ) | |
| RPG | RPG |
Compared to OPM, ILE provides RPG users with improvements or enhancements in the following areas of application development:
Each of the above areas is explained briefly in the following paragraphs and discussed further in the following chapters.
