Prerequisites

You must have attended these courses (or have equivalent experience):

• Introduction to IBM i for New Users (OE98G)
• IBM i Technical Introduction  (OL4AG)
• RPG IV Programming Fundamentals Workshop for IBM i (AS06G)

You should be able to:

Audience

This course is the second in a series of two classes designed for programmers who want to learn to code using the IBM i ILE RPG IV language. Previous programming experience using RPG IV is mandatory before enrolling in this course. The student should have attended RPG IV Programming Fundamentals Workshop for IBM i (AS06G).

Previous techniques and the maintenance of programs written using legacytechniques are not covered in the classroom.
