Course Outline:

ILE is now covered on the Crossover to modern RPGLE course although we can still run this as a standalone course. The Integrated Language Environment (ILE) is a programming technique that allows the modular development of applications. It applies many of the techniques of object orientation and therefore provides a gradual transition to the eventual deployment of Java. RPG and CL both participate in ILE. This course is aimed at developers already using RPGLE and who will be using ILE as the programming model to create re-usable program modules.

Pre-requisites:

Delegates must be already developing in RPGLE. RPGLE is taught on the Programming courses RPGIV Programming (ISR4P) and Advanced RPGIV Programming (ISR4A). Experienced RPG/400 programmers must attend the RPGIV Crossover course (ISR4X) prior to attending this course and it is recommended to have suitable hands on experience after attending the RPGIV Crossover course and before attending this course.
