Description

This course teaches programmers who are familiar with another language, but who are new to iSeries RPG IV (version 5), the basics of the RPG IV language. 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. The Moving from RPG/400 to iSeries and AS/400e RPG IV class (OE85/S6126) is designed to satisfy this need. This course is too basic for experienced RPG III programmers.
Note: The term RPG/400 refers to both System/38 RPG as well as AS/400 RPG/400
This class is a comprehensive exposure to the basic features and functions of RPG IV for Version 5. It does not introduce either information processing or programming in general. Students who are new to programming should attend other classes that are offered by local technical colleges or self study methods. This class 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 5 compiler.

Audience

This course is the first in a series of three classes designed for programmers who are new to RPG IV. Basic programming experience is required. The student should have had attended at least an introductory course to programming such as one of those available at technical colleges. The student will not be taught the concepts of programming. This course is not designed for RPG III (RPG/400) programmers who want RPG IV skills.
Note: This course focuses entirely on the latest features of the RPG IV for Version 5 compiler and the techniques that this compiler provides.
Previous techniques and the maintenance of programs written using legacy techniques 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.

Prerequisites

Before attending this course, the student should be able to:

- Use a Windows based PC
- Run PC applications using menus, icons, tool bars, etcetera
- Write a simple program in another high level language (for example, COBOL, BASIC or RPG II)
- Use basic OS/400 navigation tools including:
- Use and prompt CL commands
- Use online Help
- Manage output using WRKSPLF and related commands
- Perform basic problem determination using DSPMSG, DSPJOB, and so forth
- Use and display iSeries print queues
- Use basic CL commands such as WRKJOB and DSPMSG.
- Use the Program Development Manager, Source Entry Utility to create and maintain DDS
- Create and maintain physical and logical files
Students must have attended these courses:
- Introduction to iSeries and AS/400e for New Users (OE98/S6108)
- iSeries and AS/400e Application Programming Facilities Workshop (OL49/S6149)
or have equivalent experience. Attendance at CODE/400 - Basic (AS12/S6186) is desirable but not mandatory. Please note that this course requires a background in COBOL or RPG. Experience with Printer and Display files prior to attending this class is beneficial as well.
