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).

Covering the basics of Control Language (CL) programming as well as the latest CL features--including new structured-programming capabilities, file-processing enhancements, and the Integrated Language Environment--this resource is geared towards students learning CL. The book guides readers towards a professional grasp of CL techniques, introducing complex processes and concepts through review questions, hands-on exercises, and programming assignments that reinforce each chapter's contents. In addition to 25 chapters that cover CL from start to finish, a comprehensive appendix with condensed references to the most commonly used CL commands is also included along with two additional appendixes that cover the essentials of programming tools and debugging.

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.

A comprehensive introduction to IBM i—the operating system that runs on IBM's midrange computer systems (System i, iSeries, AS/400)—and its facilities, this in-depth resource uses step-by-step exercises, review questions, and chapter labs to teach new programmers the latest system concepts and tools. Reflecting system changes that have occurred since 2000, topics include Rational Developer for Power (RDP), RDP Screen Designer and Report Designer, IBM i Access for Windows, IBM i Access for Web, IBM DB2 Web Query for i, and Remote System Explorer (RSE).

A comprehensive resource that can be used by RPG programmers as they advance from basic subfile usage to more advanced programming, this manual offers concepts, explanations, and practical examples that reflect current trends. With downloadable templates that include both the DDS and RPG IV code, this resource provides the techniques and styles-from basic single-page displays to powerful methods such as recursion, data queues, and embedded SQL-that enable RPG programmers to become subfile masters. With updated code that shows modern methods, such as ILE strategies and free-format RPG, this reference offers a bounty of practical examples and advanced techniques.
