RPG IV Programming Advanced Workshop for IBM i

• Use address pointers and user spaces in RPG IV programs
• Write and maintain display programs using subfiles
• Develop ILE modular objects and package them in service programs
• Use the IBM i debugger with RPG IV programs
• Explain the behavior of error handling and percolation in ILE
• Code an ILE error handling program
• Call application program interfaces (APIs) from RPG IV program
• Use C functions in RPG IV programs
• Parse XML in RPG IV programs

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.

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:

• Use a Windows-based PC
• Run PC applications using menus, icons, tool bars, and so forth
