ILE RPG IV Advanced Programming (Part 2 of 2 Courses) Course

This class is designed for RPGIV programmers, who can write RPG IV programs using the iSeries RPG IV compiler (Version 5), and need to learn additional skills and techniques.  Trained programmers learn to develop and maintain RPG IV programs of an advanced level using the latest features and techniques available in the Version 5 compiler.

Participants learn programming in the Integrated Language Environment (ILE), managing the environment, and ILE objects.  Design applications using ILE programs and Service programs are discussed and attendees also discover the uses and tactics of activation groups and job management.  Finally, participants will learn to understand the MVC application design methodology.

This course is designed for experienced RPG IV programmers or those who have completed the RPGIV Intro class and the ILE programming class.

Upon completion of this course, the participants will be able to:
> Display file POP-UP windows
> Write interactive programs that support inquiry of subfiles  in pop-up windows
> Write interactive programs that support maintenance of subfile records
> Use pointer based arrays and data structures in RPG IV programs
> Develop RPG IV programs that perform error handling of common errors and exceptions
> Use prototyping to call other programs
> Write RPG IV subprocedures
> Write Integrated Language Environment (ILE) modules and include those modules in program objects using bind by copy and bind by reference
