Subfiles in Free-Format RPG: Rules, Examples, Techniques, and Other Cool Stuff - Tapa blanda

A comprehensive resource that can be used by RPG programmers as they advance from basic subfile usage to more advanced programming, this manual offers concepts, explanations, and practical examples that reflect current trends. With downloadable templates that include both the DDS and RPG IV code, this resource provides the techniques and styles—from basic single-page displays to powerful methods such as recursion, data queues, and embedded SQL—that enable RPG programmers to become subfile masters. With updated code that shows modern methods, such as ILE strategies and free-format RPG, this reference offers a bounty of practical examples and advanced techniques.

Kevin Vandever began his information technology career in 1984 Once a young, promising RPG programmer and consultant, he cranked out code, spoke at conferences, wrote articles, penned columns, and published the occasional book. Then, he moved into management. Now Kevin reviews code, approves conferences, and occasionally reads articles, columns, and books. His days are filled with words and phrases like "budgets," "status," "deadlines," and "resource constraints" and no longer with technically charged words and phrases such as "loop," "pointer," "compile," and "Who needs to test?" But no matter how far into management he's gone, Kevin still finds time to interject into every single technical discussion-no matter what the technology, language, or system-the point that the issue could probably be solved using subfiles in RPG.
