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.

Written especially for programmers adopting a free-format style, this manual explores the role of functions in writing RPG IV programs. Demonstrating the potential of functions, many topics are explored such as details about existing RPG IV built-in functions, writing new functions, using ILE concepts to use C functions, and utilizing IBM API’s functions. Explaining how to write small programs, either as sub-procedures or modules, and how to gather those parts together to make programs that are easy to write and maintain, this is a natural next step for programmers familiar with a free-format style of coding.

Application development is a key part of IBM® i businesses. The IBM i operating system is a modern, robust platform to create and develop applications. The RPG language has been around for a long time, but is still being transformed into a modern business language. This IBM Redbooks® publication is focused on helping the IBM i development community understand the modern RPG language. The world of application development has been rapidly changing over the past years. The good news is that IBM i has been changing right along with it, and has made significant changes to the RPG language. This book is intended to help developers understand what modern RPG looks like and how to move from older versions of RPG to a newer, modern version. Additionally, it covers the basics of Integrated Language Environment® (ILE), interfacing with many other languages, and the best tools for doing development on IBM i. Using modern tools, methodologies, and languages are key to continuing to stay relevant in today's world. Being able to find the right talent for your company is key to your continued success. Using the guidelines and principles in this book can help set you up to find that talent today and into the future. This publication is the result of work that was done by IBM, industry experts, business partners, and some of the original authors of the first edition of this book. This information is important not only for developers, but also business decision makers (CIO for example) to understand that the IBM i is not an 'old' system. IBM i has modern languages and tools. It is a matter of what you choose to do with the IBM i that defines its age.

Examples also show how to improve programming efficiency in RPG IV. RPG IV by Example focuses on application situations familiar to experienced programmers. RPG IV by Example is an invaluable coach for any RPG programmer at any experience level. Longtime programmers will find out how RPG IV lets you continue to take advantage of tried-and-true methods while adopting important timesaving capabilities. RPG newcomers will learn from examples how to create RPG IV applications. The emphasis is on practical solutions that programmers need every day. The authors integrate this information into 15 chapters featuring discussions of data definition, database file processing, arithmetic and move operations, indicator functions, structured programming, array and table processing, pointer functions, and ILE and non-ILE program calls.

From the basics of programming in the Qshell on iSeries to complete coverage of previously undocumented topics, programmers will not only learn the Qshell more easily than they can with the Qshell manual from IBM, they will also learn practical applications of using the Qshell effectively. Written for users who are more comfortable with DDS, CL, and RPG as well as those using modern languages such as C and Java, this book allows those who are unfamiliar with Unix to easily learn this technology, which otherwise might be foreign to them. Although written specifically for iSeries programmers, the information gleaned here will be largely applicable to the shells for Linux and Unix, so programmers not familiar with those platforms will find those shells much easier to learn after learning Qshell.

IBM i professionals are known for their dedication to IBM’s midrange computing platform. But while IBM’s technology has evolved, not all IBM i programmers’ skills have kept pace. If you are part of this group--an IBM i programmer who has not yet made the leap to coding with the latest technologies--ILE RPG, free-format RPG, and Model-View-Controller (MVC)--or someone who needs more practice with them, this is the book for you. "21st Century RPG: /FREE, ILE, and MVC" has a simple mission: to educate programmers who have been left behind in the IBM i’s evolution, so they can 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. The book helps readers gain confidence in areas that may be new to them, with examples that let them practice what they’ve learned. Shirey has structured the book so that whether you’re running the latest IBM i technology or an older version, you will learn ways to improve your coding and applications, and get comfortable with writing programs using ILE RPG, free-format, and MVC.
