RPG IV Programming Fundamentals Workshop for IBM i Schulung
Basics of the IBM i RPG IV programming language
This course teaches the basics of the IBM i RPG IV programming language. It is the first of three courses that should be attended in sequence.
This course is a comprehensive exposure to the basic features and functions of RPG IV for Version 7. It does not introduce either information processing or programming in general. Students who are new to programming should attend other courses that are offered by local technical colleges or self-study methods.
This course is designed to enable a trained programmer to develop and maintain simple RPG IV programs written using the latest features and techniques available in the Version 7 compiler.

This course is the first in a series of courses designed for programmers who are new to RPG IV. Basic programming experience is required. 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 the i system should also attend this course. Examples of other programming languages are BASIC, COBOL or RPG II.
This course is not designed for RPG III programmers who want to learn RPG IV. This course is too basic for experienced RPG III programmers.
This course focuses entirely on the features of the RPG IV Version 7 compiler and the techniques that this compiler provides. Features of V7 are discussed.
Previous techniques and the maintenance of programs written using legacy techniques, such as fixed format calculations, are not covered in the classroom. Some additional material and the bibliography will assist the new RPG IV programmer in the maintenance of legacy applications.
You should be able to:
- Use a Windows-based PC
- Run PC applications using menus, icons, toolbars, and so forth
- Write a simple program in another high-level language (for example, CL, COBOL, BASIC or RPG II)
- Use basic IBM i tools, including:
- CL commands
- Online Help
- WRKSPLF and related commands to manage output
- WRKJOB, DSPMSG, DSPJOB commands and so forth to perform basic problem determination
- Use and display i print queues
- Use the Program Development Manager/Source Entry Utility or the RSE/LPEX editor to create and maintain DDS
- Create and maintain physical and logical files
You must have attended this course:
- System Operator Workshop for IBM i (AS24D2DE)
Experience with Printer and Display files prior to attending this course is beneficial as well.
