RPG TnT

Bob Cozzi's resume is truly impressive: nearly 20 years of AS/400, iSeries, and System i experience; more than a decade of RPG IV development; and nearly 30 years of RPG programming. He has confronted, evaluated, and circumvented nearly every roadblock RPG programmers can experience. In this book, he not only blasts through RPG IV's shortcomings, but he also creates extensions that provide features that are simply not available in standard RPG IV.

With these 101 Dynamite Tips 'n Techniques, Cozzi provides the solutions to dozens of technical dilemmas, gives you insights into resources formerly available only to a select few, and exposes RPG IV extensions that use his vast knowledge of System i MI instructions--all with easy-to-use wrappers that even the most inexperienced RPG IV programmer can implement. Lift the code right out of the book and into your applications!

RPG TnT provides a nearly endless supply of must-have solutions and simple yet powerful RPG tips and tools.
