Programming in ILE RPG - Softcover

"RPG has been a mainstay on IBM i for many decades. With IBM i now supporting many open source languages, there will be a new cross-section of developers being exposed to the machine, and we need to teach them the latest features of RPG for fruitful coexistence. That's where this book shines. Jim and Bryan have expertly put together a book to meet the needs of one learning modern RPG, complete with 100% free-form and modular coding practices (e.g., service programs), . . . how to use the latest tools like RDi, . . . and commentary on best practices, so readers can make decisions based on sage advice." --Aaron Bartell, Director of IBM i Innovation, Krengel Technology

"We have been using the earlier versions of this book as part of our 'Introduction to RPG IV' classes for many years now. This latest version includes the modern free-format declarations and other recent language enhancements as well as covering essentials such as building and using Service Programs. It is an essential guide to the language as well as being a great reference document as students progress in their use of the language. Our only criticism is that this version renders our existing inventory obsolete! Highly recommended." --Jon Paris and Susan Gantner, Partner400 owners and IBM i educators
