Book Description
Bryan Meyers has updated his indispensible guide to RPG IV to cover RPG's latest enhancements to the language. Free-form calculation specifications, new built-in functions, improved error handling, and more -- all the V5 goodies are in here, demystified through clear explanations and numerous coding examples. RPGIV Jump Start presents RPG IV from the perspective of a programmer who already knows RPG III, pointing out the differences between the two versions of the language and demonstrating -- through numerous coding examples and suggestions -- how to take advantage of the new syntax and function. This new edition gives you everything you need to know to get going quickly with the new RPG. New chapters bring you up to speed on free-form expressions and show you how to get the most from RPG's expanded array of built-in functions. You'll see the new free-form coding at work throughout the book. Best of all, a new appendix provides a complete, integrated reference to every one of RPG IV's opcodes and BIFs -- a resource even veteran programmers will appreciate. Book jacket.
