This standard reference manual presents the format and use of the COBOL programming language, incorporating Third Standard COBOL, also known as COBOL-85, which is the latest standard form of the language. Using this book in conjunction with the documentation for your compiler, your programs will be transportable to other compilers that conform to the new standard. Chapter 1 summarizes basic concepts and features of COBOL programs. Chapters 2 through 5 cover the COBOL-85 components in each of the four main divisions in the Nucleus module. Chapter 6 covers the use of the Interprogram Communication module. Chapter 7 discusses the use of file I/O: it deals with the Sequential, Relative, and Indexed modules. Chapter 8 explains the use of the Sort/Merge module. The remaining COBOL modules are covered briefly in Appendix C.
This comprehensive reference guide presents all the facets of the Pascal language in an easily accessible manner. Many fully tested program segments that illustrate all of the features of the Pascal language and the source code for a powerful spelling checker is presented in its entirety. The latest changes to the Pascal language are presented and summarized. This package illustrates many low-level programming techniques applicable in an extended Pascal dialect, Meta Pascal and presents important non-standard features of Turbo Pascal, UCSD Pascal, Meta Pascal and Microsoft Pascal. Chapters cover programming style, lexical structure, input and output in Pascal, data abstraction in Pascal, recent changes to Pascal - the ISO standard, Turbo, UCSD and Microsoft Pascal, differences between Pascal and Modula-2, Turbo Pascal procedures and functions, Turbo Pascal case study - animation graphics, other Pascal extensions and bit and byte manipulations. Appendixes contain syntax of Pascal, ASCII character set, Turbo Pascal compiler directives, references and resources.

Mainframe computers play a central role in the daily operations of many of the world's largest corporations. Batch processing is still a fundamental, mission-critical component of the workloads that run on the mainframe. A large portion of the workload on IBM® z/OS® systems is processed in batch mode. This IBM Redbooks® publication is the fourth volume in a series of four. They address new technologies introduced by IBM to facilitate the use of hybrid batch applications that combine the best aspects of Java and procedural programming languages such as COBOL. This volume focuses on the latest enhancements in IBM IMSTM batch support. IMS has been available to clients for 45 years as IMS Transaction Manager, IMS Database Manager, or both. The audience for this book includes IT architects and application developers with a focus on batch processing on the z/OS platform.
This IBM® Redbooks® publication provides information about the new Java virtual machine (JVM) server technology in IBM CICS® Transaction Server for z/OS® V4.2. We begin by outlining the many advantages of its multi-threaded operation over the pooled JVM function of earlier releases. The Open Services Gateway initiative (OSGi) is described and we highlight the benefits OSGi brings to both development and deployment. Details are then provided about how to configure and use the new JVM server environment. Examples are included of the deployment process, which takes a Java application from the workstation Eclipse integrated development environment (IDE) with the IBM CICS Explorer® software development kit (SDK) plug-in, through the various stages up to execution in a stand-alone CICS region and an IBM CICSPlex® environment. The book continues with a comparison between traditional CICS programming, and CICS programming from Java. As a result, the main functional areas of the Java class library for CICS (JCICS) application programming interface (API) are extensively reviewed. Further chapters are provided to demonstrate interaction with structured data such as copybooks, and how to access relational databases by using Java Database Connectivity (JDBC) and Structured Query Language for Java (SQLJ). Finally, we devote a chapter to the migration of applications from the pooled JVM model to the new JVM server run time.
In this IBM® Redbooks® publication, we attempt to provide fresh insight into a problem domain that, in the authors' opinions, has been pushed to the back burner of technology writing for far too long—the domain of z/OS® (traditional) mainframe maintenance and production support. Since the mid-1980's, outside of a few websites and publications, this still-critical area of software has barely even received lip service by the world of mainstream technology media. In a small way, we are attempting address this situation. In this book, we provide information in "what and how to" sections on the value of z/OS maintenance and support—not the value of the software, which is hardly in question, but the value of the software developers, and how they collaborate, analyze, code, and test the applications, fixes, and enhancements under their responsibility. We present new 21st Century tools to help them achieve their goals more easily and effectively. These tools integrate and provide a 1 + 1 + 1 = 5 value-proposition, for companies that are still doing work the way they did when in the mid-1970's, when Gerald Ford was president of the United States. We are also describing, to a lesser extent, how you can effectively integrate the new tools with your existing development software stack, in order to find points of complimentary functionality. And we describe the new agile development and maintenance methodologies, and best practices for tools use and adoption. We hope that you find this work useful, and perhaps that it can fuel more discussion, future Redbooks publications, and other publications by IBM, or any vendor or group interested in this critical and vastly under-acknowledged technology domain.
Here's one of the singular references providing on-the-mark coverage of application development based on thhe Component Object Model (COM) and Microsoft Transaction Server (MTS). DESIGNING COMPONENT-BASED APPLICATIONS demonstrates the principles of effective COM-driven design and MTS deployment through in-depth examination of Island Hopper, a joint project of the Microsoft COM and Microsoft Visual Studio design teams. This full-featured enterprise application was built using a practical set of development guidelines field-tested by Microsoft consultants on a variety of 3-2-1 projects (3 tiers, 2 developers, 1month). As you focus on individual facets of the model application, you're also learning how to apply this proven methodology to quickly design, test, debug, and deploy your own multitier, COM-based programs.
The challenges of designing, building, and maintaining large-scale, distributed enterprise systems are truly daunting. Written for all IT professionals, The Complete Book of Middleware will aid in resolving new business objectives, new technologies, and vendor disputes. This book focuses on the essential principles and priorities of system design and emphasizes the new requirements brought forward by the rise of e-commerce and distributed integrated systems. This reference highlights the changes to middleware technologies and standards. It offers a concise overview of middleware technology alternatives and distributed systems. Many increasingly complex examples are incorporated throughout and the book concludes with guidelines on the practice of IT architecture. Performance considerations such as caching and monitoring are reviewed and the appendix includes middleware resources and new modeling standards. The scope includes traditional middleware and also next-generation techniques that serve to glue disparate systems in the ever-expanding world of distributed network systems. Provided with concepts, principles, and alternatives discussed in The Complete Book of Middleware, systems architects, systems analysts, systems designers, systems developers, and programmers, can proceed with greater confidence in designing complex enterprise systems.
