Book SynopsisApplication 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 communicatewith other systems, such as PCs, using socketsTable of ContentsChapter 1: API Fundamentals Chapter 2: Retrieve APIs Chapter 3: List APIs Chapter 4: Command Processing APIs Chapter 5: Object APIs Chapter 6: Data Queue APIs Chapter 7: Database File APIs Chapter 8: Date and Time APIs Chapter 9: Character Conversion APIs Chapter 10: Message APIs Chapter 11: Encryption APIs Chapter 12: Security APIs Chapter 13: Work Management APIs Chapter 14: Integrated File System APIs Chapter 15: Socket APIs Chapter 16: Odds & Ends Appendix A: About the CD-ROM Appendix B: ILE APIs Appendix C: COBOL APIs Appendix D: Answers to End-of-Chapter Questions

Book SynopsisWant to get better at coding Elixir? Write a hardware project with Nerves. As you build this binary clock, you'll build in resiliency using OTP, the same libraries powering many commercial phone switches. You'll attack complexity the way the experts do, using a layered approach. You'll sharpen your debugging skills by taking small, easily verified steps toward your goal. When you're done, you'll have a working binary clock and a good appreciation of the work that goes into a hardware system. You'll also be able to apply that understanding to every new line of Elixir you write. Combining software with hardware can be frustrating, but you can become proficient in no time by taking a simple, logical approach. Blinking a single LED is the traditional hello-world of embedded systems. Building your own binary clock is the logical next step. It blinks groupings of LEDs based on the system time. This guide walks you through a working project using the techniques used by experts who build software for hardware every day. This common sense project moves forward in tiny, logical steps. As you progress, you can verify each step before moving on to the next. You don't have to be a Nerves novice to benefit from this project. Become a better Elixir programmer as you build your own desktop showpiece. With a layered approach to software design, you'll learn to control the complexity of your programs the way the experts do by focusing on one small slice of your system at a time. When you're done, you'll have your own binary clock, and also more of the tools you need to design and build your own Nerves and Elixir projects. You'll also be a better programmer with a deeper appreciation of layering techniques for controlling complexity. What You Need: This project is for Elixir developers who want to get started with Nerves, or improve their skills. The project is designed for Elixir 1.11 and Nerves 1.7, but later versions will probably work as well with slight modifications. The project uses a Raspberry Pi zero with a set of components. With slight modifications, you can make this book work with other components as well.

Book SynopsisOne critical barrier leading to successful implementation of flexible manufacturing and related automated systems is the ever-increasing complexity of their modeling, analysis, simulation, and control. Research and development over the last three decades has provided new theory and graphical tools based on Petri nets and related concepts for the design of such systems. The purpose of this book is to introduce a set of Petri-net-based tools and methods to address a variety of problems associated with the design and implementation of flexible manufacturing systems (FMSs), with several implementation examples.There are three ways this book will directly benefit readers. First, the book will allow engineers and managers who are responsible for the design and implementation of modern manufacturing systems to evaluate Petri nets for applications in their work. Second, it will provide sufficient breadth and depth to allow development of Petri-net-based industrial applications. Third, it will allow the basic Petri net material to be taught to industrial practitioners, students, and academic researchers much more efficiently. This will foster further research and applications of Petri nets in aiding the successful implementation of advanced manufacturing systems.Table of ContentsFlexible manufacturing systems - an overview; Petri nets as an integrated tool and methodology in FMS design; fundamentals of Petri nets; modelling FMS with Petri nets; FMS performance analysis; Petri net simulation and tools; performance evaluation of pull and push paradigms in flexible automation; augmented-timed Petri nets for modelling breakdown handling; real-time Petri nets for discrete event control; comparison of real-time Petri nets and ladder logic diagrams; an object-oriented design methodology for development of FMS control software; scheduling using Petri nets; Petri nets and future research.
