Subfiles in RPG IV

For each topic, this book offers concepts, explanations, and practical eximples you can use as templates for further development. These templates are fully functional programs that include both DOS and RPG IV code-from basic single-page display subfiles to powerful techniques such as recursion, data queues, and embedded SQL. As an added bonus, each example is included on the accompanying CD-ROM, ready to copy to your AS/400.

Mastering subfiles is often the defining moment in an RPG programmer's career. This book provides you with the concepts, styles, and advanced techniques-using RPG IV and ILE-that will enable you to become a subfile master in your own right.
