Training IBM i Mastering RPG IV Programming

Course Description

RPG IV Programming Workshop v-5 for System-i from Basic to Advance

Duration: 5 days

Purpose
This course teaches from basics to advance of the i5 (iSeries) RPG IV programming language.
This class is a comprehensive exposure from basic features and functions to advance of
RPG IV for Version 5. It does not introduce either information processing or programming in general.
This class is designed to enable a trained programmer to develop and maintain RPG IV programs written using the latest features and techniques available in the Version 5 compiler.

Audience
The student should have attended at least an introductory course to programming such as one of those available at technical colleges. The student is not taught the concepts of programming.
Experienced programmers who are new to i5 (iSeries) should also attend this class.
Examples of other programming languages are BASIC, COBOL or RPG II.
This class is not designed for RPG III programmers who want to learn RPG IV.

Notes:
This course focuses entirely on the features of the RPG IV Version 5 compiler and the
techniques that this compiler provides. Features of V5 are discussed.
Previous techniques and the maintenance of programs written using legacy techniques, such as fixed format calculations, are not covered in the classroom.
