RPG IV introduced the concept of built-in functions to the RPG programmer, but many still do not fully appreciate the power and flexibility they can add to your applications. As powerful as this support is though, it still can't provide every possible function that your applications will need. Enter user-defined procedures. Introduced in V3R6, these open up completely new ways of building applications. You'll be introduced to the basics of writing Subprocedures, and learn how they can help you build more powerful, modular applications.

In this session you will learn:
1. How to Code your own "built-in functions".
2. Use basic prototype options to increase the versatility of your subprocedures.
3. Add a "must have" skill to your resume.
