Introduction

You will be shown how to enhance your RPG4 skills to develop more complex applications in RPG4. The course builds on existing RPG4 programming skills, and shows the RPG4 programmer how to use many more of the languages features.

What you will learn

On completion of this course, you will be able to:

Use data areas and data structures.
Code and use execution time, compile time and multi-dimensional arrays
Use pointers and storage management.
Use subprocedures within RPG IV programs.
Pass parameters to and from subprocedures.
Use commitment control in update programs.
Use and define activation groups.

Who should attend

Programmers, programmer/analysts and senior programmers who develop and maintain applications using RPG4 on the iSeries.

Pre-requisites / Follow on courses

The iSeries (AS/400) RPGIV Programming course should be attended prior to this course. A period of hands on programming using RPGIV to write and maintain RPGIV programs must follow this course. This should ensure that delegates could write new RPGIV programs. Delegates may attend the iSeries ILE PROGRAMMING course after this course.
