RPG TnT

Bob Cozzi’s résumé 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. 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.

With this book, you’ll learn how to:

• Implement an alternative to QCMDEXC
• Use QUALIFIED and nested data structures
• Embed compiler parameters into source members
• Calculate end-of-month dates and day-of-week names
• Create an auto-extend user space
• Use C runtime functions in RPG IV
• Use the secret ‘X’ edit code to convert numeric to character
• Improve performance when accessing user space data
• Retrieve the function key used on a display file
• Use EXTFILE to avoid needless overrides
• Debug variables that have debugger command names
• Read and encrypt save files in RPG IV
• And a whole lot more!

An RPG programmer since 1978, Bob Cozzi is the author of several books on RPG programming, including The Modern RPG IV Language -- the most widely used RPG reference manual in the world.
