This new book takes a fresh approach to Integrated Language Environment (ILE). Learn the fundamentals of the AS/400’s ILE by following working examples that illustrate the ins and outs of this powerful programming model. NEWS/400 Technical Editor Mike Cravitz demystifies such ILE concepts as service programs, subprocedures, activation groups, and more. CD included.
Book Description
Editorial Reviews
From the Author
A number of books and articles have been published on the subject of ILE. I didn't want to write just "another one.” This book is short but it gives the RPG programmer the essentials. The code shown in the book is working and tested and is included with the attached CD. The code is fully commented with installation instructions as well as the usual explanatory comments.
The book's scope is ILE and the ILE aspects of the RPG IV language. So not only will you learn about static binding, service programs, and condition and cancel handlers, but also you will learn specifically how these things are accomplished in the RPG IV language.
I am particularly proud of Chapter 5 where I unravel the mysteries of activation groups. Nowhere else in my investigations have activation groups been adequately explained. Read Chapter 5 and you will understand them and their (sometimes unexpected) side effects. Read the book and you will be well on your way to fully exploiting ILE.
From the Inside Flap
Here is everything you need to know to get a grip on the AS/400’s Integrated Language Environment (ILE). Learn by following working examples that illustrate the ins and outs of this powerful programming model. Major topics include:
ILE program structure, which is quite different from the OPM program structure
Bind by copy, and when this mechanism can be useful in your system design
ILE RPG subprocedures
Service programs and service program signatures
Activation groups
ILE exception handling
How to write your own ILE condition handler
How to use ILE cancel handlers to avoid problems when your programs are canceled
ILE by Example presents more than mere theory. It includes plenty of working examples to illustrate the fundamental aspects of ILE. The CD that accompanies this book contains all but the most trivial of the sample programs. Each source on the CD has explicit instructions regarding its use and any other sources that must be used in conjunction with it.
