21st Century Rpg - /Free, Ile, and Mvc


Book Description

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).




Free-Format RPG IV


Book Description

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.




Mastering IBM I


Book Description

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).




Control Language Programming for IBM I


Book Description

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.




Subfiles in Free-Format RPG


Book Description

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.

Developing Business Applications for the Web


Book Description

This book focuses on using common Web tools to develop business applications. Professional business programmers who are new to Web development will quickly acquire the relevant information they need, starting with HTML and CSS. The book goes beyond simple HTML and introduces other common Web technologies, including Java Server Pages (JSP), PHP, ASP.NET, and JavaScript. The book shows how those technologies interact with HTML and how developers can use them to develop and deploy business applications that users access via the Web. This book is written by business programmers and educators for business programmers. It is not just an introduction to HTML, but an introduction to the most common tools any business programmer needs to develop browser-based applications. Upon completion of the book, a business developer or student will have learned to develop and implement a completed browser-based business application.




Smarter Business: Dynamic Information with IBM InfoSphere Data Replication CDC


Book Description

To make better informed business decisions, better serve clients, and increase operational efficiencies, you must be aware of changes to key data as they occur. In addition, you must enable the immediate delivery of this information to the people and processes that need to act upon it. This ability to sense and respond to data changes is fundamental to dynamic warehousing, master data management, and many other key initiatives. A major challenge in providing this type of environment is determining how to tie all the independent systems together and process the immense data flow requirements. IBM® InfoSphere® Change Data Capture (InfoSphere CDC) can respond to that challenge, providing programming-free data integration, and eliminating redundant data transfer, to minimize the impact on production systems. In this IBM Redbooks® publication, we show you examples of how InfoSphere CDC can be used to implement integrated systems, to keep those systems updated immediately as changes occur, and to use your existing infrastructure and scale up as your workload grows. InfoSphere CDC can also enhance your investment in other software, such as IBM DataStage® and IBM QualityStage®, IBM InfoSphere Warehouse, and IBM InfoSphere Master Data Management Server, enabling real-time and event-driven processes. Enable the integration of your critical data and make it immediately available as your business needs it.
