Here is your guide to mastering hundreds of new APIs available on the iSeries and AS/400 to effectively solve business problems. RPG wizards Doug Pence and Ron Hawkins reveal how to use APIs for everything from extracting information from deep within the recesses of your system to delivering pages to the World Wide Web. Each chapter is full of real business-world examples that you can modify and use in your own environment. 
In recent years, the business world has realized the impact information systems have on business effectiveness. As a result, you are now expected to use high-level encryption to store sensitive information, to write interfaces between Microsoft Windows and AS/400 RPG applications, and to integrate your business applications with the Web. This book will show you how you can use APIs to do all of this and more. You will come to realize that there is nothing you cannot do with iSeries and AS/400 APIs if you know where to look. When you have completed this book, you will be able to: Use APIs to write Web pages to the Internet from your iSeries and AS/400 RPG IV programs, process standard list APIs and asynchronous open list APIs, build, populate, and work with user spaces, create dynamic indices with user index APIs, write programs that enable your iSeries and AS/400 to communicate with PCs using Sockets, use APIs to retrieve system values, job information, and job queue information, use APIs with user data queues and remote data queues, handle errors using both the standard error data structure and global variables, use message-handling APIs, use APIs to read and write encrypted passwords, process spooled files with APIs, and use and manage validation lists.

This book is practically mandatory for any RPG programmer. If you're a novice programmer, you will be able to learn from the experts how to do things right the first time. If you're a veteran, you will find fresh, new ideas and techniques that will help you continue to grow in your career. RPG IV at Work opens doors and unlocks information, helping you take full advantage of the complete range of RPG IV capabilities. Doug Pence and Ron Hawkins have spent the last two decades accumulating tips, tools, and techniques that make RPG the best that it can be. From designing software to attaining maximum performance to using advanced problem-solving tools, this book presents a wide range of important topics. It offers in-depth, practical coverage of basic subjects--such as data structures, string handling, and subfiles--and also tackles the more intricate subject areas, such as APIs, prototyping, and journaling as a debugging tool. It covers built-in functions (BIFs), data types, and subprocedures. From coding to compiling, this book has tips for RPG programmers of every level. There are even tools and utilities from Doug and Ron's own toolbox-tools they have designed to improve their productivity and extend their effectiveness as programmers. RPG IV at Work is a complete rewrite of Pence and Hawkins' best-selling 1996 book Power RPG IV. Although much of the basic material has remained, Doug and Ron have reviewed all the code and all the techniques and updated them with newer techniques and additions to the RPG language throughout the book. They have also included additional sections to cover new facilities in the language. Have you ever wished you could just sit down and talk to a real RPG IV programming guru? This book is the next best thing. Doug and Ron tell you how they use these techniques, why they program tasks in specific ways, and why they don't choose other options. In fact, this book just might bring you up to guru status yourself. Upon completion of this book, you will be able to master: advanced techniques that give your programs real power and pizzazz, a sophisticated array and string handling techniques, design concepts that enhance system performance, ILE concepts (what you really have to know), command processing and system APIs, subfiles with all the bells and whistles, information data structures and error handling, and effective and efficient debugging. This book will also teach you to master Windows and menu bars, powerful uses for data structures and data areas, complex manipulation, formatting, and management of date data types, the power of prototyping, procedures, and subprocedures, and the all-time favorite utilities from Doug and Ron's personal toolbox.

Application Program Interfaces (APIs) are powerful, built-in tools used to solve business problems. Many System i programmers, however, do not have a working knowledge of the APIs available within i5/OS. Worse still, programmers who are familiar with the use of APIs may not be taking full advantage of the APIs and processing techniques available to them.
In this book, author and noted IBM API expert Bruce Vining is your guide to making sense, and effectively mastering, the wide variety of APIs available with System i. Each chapter is full of real business-world examples that you can modify and use in your own environment.
In recent years, the business programmer has had to integrate applications—often from different operating systems and programming platforms—using different languages to integrate business rules and requirements. APIs allow you to gain access to the underlying structure of an application. With this book you will soon realize that APIs are among the most powerful tools in your toolbox.
New for this edition:
• New chapters covering topics such as exit point concepts, Integrated File System, date and time, cryptographic services, TCP/IP, and more 
• Sorting, character data conversion, and user application information 
• APIs are covered in depth 
• Fully updated code on previous APIs to bring them up to newer standards 
• Updates to API changes since the previous edition 
• Modernized RPG code to demonstrate current coding style 
• An Appendix with COBOL examples and implementation including API equivalents for RPG support of memory management, bit testing, edit words, and more 
• Check Your Knowledge tasks at the conclusion of each chapter with solutions provided in RPG and COBOL Write client and server applications that enable your System i to communicate
with other systems, such as PCs, using sockets
