Annotation A hands-on approach to learning library-object structure, utilities and database management capabilities, application development tools, and OS/400 Control Language (CL), for the AS/400 computer. Twelve lessons, based largely on lab exercises, teach students how to communicate with the system, and use its many features, including CL, Query/400, logical files, DFU, SQL, and SDA.

The AS/400 Control Language (CL) is a set of commands that provide the primary interface between users and the system. Collectively, CL has more than a thousand commands, each of which is designed to perform a specific system, operational, or programming task. This book is a complete tutorial and easy-to-use reference for the AS/400 control language, together with AS/400: SYSTEM, UTILITIES, DATABASE AND PROGRAMMING by Lin & Stewart, it forms a complete tutorial and reference package for the AS/400.* covers CL commands, CL programming fundamentals, CL programming elements, calling programs and processing files, and advanced topics, such as sending messages and debugging programs.
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).
IBM and the rest of the computer industry are putting most of their DBMS development efforts into SQL. This reference provides the SQL/400 skills that a successful applications developer needs and shows how to create comprehensive, complex, and professional SQL/400 databases.
Tis guide is intended for students learning computer operations and administration on the AS/400 computer system. Offering a unique approach to learning AS/400 operations with extensive hands-on labs, self-tests, and review questions, this book uses real-world situations to enable users to be productive with AS/400 operations. This book also covers the requirements of the two IBM AS/400 certification exams: AS/400 Associate System Operator Certification (test 052) and AS/400 Professional System Operator Certification (test 053). The primary goal of this book is to teach users how to perform day-to-day operations on an AS/400 computer system, including IPL, starting and stopping the system, backup and recovery, and system cleanup. Procedures covered include creating and maintaining user environments, device configuration and management, security implementation, work and data management, and TCP/IP configuration. Console operations discussed include jobs, message handling, and working with spool files and peripheral devices. Functions of Operations Navigator are covered, and Electronic Customer Support (ECS) and PTF upgrades are also introduced.
Leverage the power of Elixir programming language to solve practical problems associated with scalability, concurrency, fault tolerance, and high availability. Key Features Enhance your Elixir programming skills using its powerful tools and abstractions Discover how to develop a full-fledged file server Understand how to use Phoenix to create a web interface for your application. Book Description Running concurrent, fault-tolerant applications that scale is a very demanding responsibility. After learning the abstractions that Elixir gives us, developers are able to build such applications with inconceivable low effort. There is a big gap between playing around with Elixir and running it in production, serving live requests. This book will help you fll this gap by going into detail on several aspects of how Elixir works and showing concrete examples of how to apply the concepts learned to a fully fledged application. In this book, you will learn how to build a rock-solid application, beginning by using Mix to create a new project. Then you will learn how the use of Erlang's OTP, along with the Elixir abstractions that run on top of it (such as GenServer and GenStage), that allow you to build applications that are easy to parallelize and distribute. You will also master supervisors (and supervision trees), and comprehend how they are the basis for building fault-tolerant applications. Then you will use Phoenix to create a web interface for your application. Upon fnishing implementation, you will learn how to take your application to the cloud, using Kubernetes to automatically deploy, scale, and manage it. Last, but not least, you will keep your peace of mind by learning how to thoroughly test and then monitor your application. What you will learn Use Elixir tools, including IEx and Mix Find out how an Elixir project is structured and how to create umbrella applications Discover the power of supervision trees, the basis for fault-tolerance Create a Domain-Specifc Language (DSL) that abstracts complexity Create a blazing-fast web interface for your application with Phoenix Set up an automatic deployment process for the cloud Monitor your application and be warned if anything unexpected happens Who this book is for Mastering Elixir is for you if you have experience in Elixir programming and want to take it to the next level. This Elixir book shows you how to build, deploy, and maintain robust applications, allowing you to go from tinkering with Elixir on side projects to using it in a live environment. However, no prior knowledge of Elixir is required to enjoy the complex topics covered in the book.
For companies moving their COBOL applications from older mainframes to AS/400, this book cover the specific tools from COBOL 400 that programmers need to convert and develop their applications.
Since reigning poker expert Phil Gordon’s Little Green Book illuminated the strategies and philosophies necessary to win at No Limit Texas Hold’em, poker has changed quickly and dramatically. Today, Pot Limit Omaha is the game of choice at nosebleed stakes. The players are aggressive, the games are volatile, the decisions are tough, and the pressure is relentless. This is Poker 2.0. In his Little Gold Book, Phil Gordon reexamines the game from the ground up. The key to competing with today’s top players is finding the post-flop edge, but to really understand this new playing style, you need to get comfortable with the underlying math. Don’t be intimidated. Gordon makes this challenging material as approachable and simple as possible. Beginning with the foundations of Poker 2.0, he unpacks the modern poker player’s tool kit, rigorously examines the new lines of play in No Limit Hold’em, dissects the fast and furious strategies of Pot Limit Omaha, and explores the winning poker mind-set that will take your game to an entirely different level. The golden age of poker is upon us. Phil Gordon’s Little Gold Book will shorten your learning curve, and if you’re willing to put in the time and the work, big bankrolls await.
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.
