RPG IV is evolving and gaining capabilities at a more rapid rate than any of today's other computer languages, and this text is comprehensive in its coverage of the specifications, operations, and functions of the language. The coverage uses V5R4 as its base release and is compatible with later releases. Free-format specifications, modular procedures, the latest built-in functions, and more are all covered in a highly approachable style, complete with numerous programming examples and support material.

The book includes complete coverage of the program development process, RPG IV specs and operations, top-down structured design, database definition and processing, and interactive applications. This edition also explains important concepts of the Integrated Language Environment (ILE), including the use of modular procedures and service programs in a modern IBM i application.

A series of appendices will prove useful not only while you are learning RPG IV but also as everyday references to RPG IV syntax elements, RPG IV style, program development tools, program debugging, and legacy syntax and techniques for use when maintaining older applications.

Upon completion of this book, you will be well-equipped to create highly effective and maintainable RPG IV programs using the latest techniques. By focusing on real-world problems, down-to-earth solutions, and the latest style techniques, this book will make you stand out in the RPG marketplace.
