This guide teaches programmers who have been left behind in the IBM i's evolution to code more productively and modernize their business applications. Shirey uses a casual, humorous teaching style to explain the concepts, along with plenty of code examples. Readers will gain confidence in areas that may be new to them and use the provided examples to practice what they've learned. The manual is structured so that whether they are using the latest IBM i technology or an older version, readers will learn methods to improve coding and applications, as well as become comfortable with writing programs using ILE RPG, free-format RPG, and Model-View-Controller (MVC).

Focusing strictly on teaching free-format RPG programming methods, this book will help programmers wishing to upgrade their skills This how-to guide offers a concise and thorough introduction to the increased productivity, better readability, and easier program maintenance that comes with the free-format style of programming in RPG IV. Although free-format information is available in IBM manuals, it is not separated from everything else, requiring hours of tedious research to track down the information needed. This book provides everything you need to know to write RPG IV in the free-format style. Author Jim Martin not only teaches rules and syntax, but also explains how this modern style of coding has the potential to improve overall programmer productivity--from initial development through maintenance. He methodically covers the many style issues, such as named indicators and built-in functions, and addresses topics including input and output, program flow, data manipulation, math operations, prototyping, and APIs. This third edition is updated to V7.1 of the IBM i operating system on IBM Power machines. An added chapter explains the new free-format H, F, D, and P specifications introduced by IBM in Technology Refresh 7, and programming examples throughout the book are updated to reflect the new specifications.

Jake and Maggy lived on a farm where they loved to sing and dance to the music from Mama's radio. Then terrible dust storms came and ruined the land. The family had no choice but to auction off the farm and make the long, hard journey west to California-away from the dust storms, where the land is still green. Along the way, Papa tries to find work, and Jake and Maggy try to help too. But what if Papa can't find a job? What if California isn't better after all? Ann Turner's dramatic story about the dust bowl, set during the Great Depression and beautifully captured in Robert Barrett's paintings, shows how one family stays together during difficult times.

Here is the ultimate guide to writing RPG IV programs with functions in the free-format style. Let RPG expert and best-selling author Jim Martin show you the way. Want to generate a random number, manipulate a character string, or determine the number of elements in a data structure? There's a function for that. Jim will even show you how to write your own custom built-in functions (BIFs). In this book, you'll discover the role of functions in free-format RPG IV. Jim explains the details of built-in functions (BIFs) and explores the use of C language functions, do-it-yourself functions (subprocedures), and prototyping and procedure interfaces for function connectivity of RPG IV main procedures with subprocedures and other modules. Because functions rely heavily on ILE, the book examines those ILE concepts that connect the parts of a multi-functional program, such as binding, import/export of data, service programs, and binding directories. In addition, you'll find how to prototype IBM's APIs.
