Kevin Vandever's Subfiles in RPG IV (MC Press, 2000) offered easy-to-understand explanations of subfile concepts plus a bounty of practical examples, advanced techniques, and other cool stuff never before seen in subfile books. Now, this popular manual has been updated from beginning to end to teach subfile concepts and programming techniques using free-format RPG. A comprehensive resource that RPG programmers can use as they advance from basic subfile usage to more advanced programming, this book offers concepts, explanations, and practical examples that reflect current trends.
