This book will teach you how to write programs in the REXX language on IBM mainframe computers. It is useful for technical, applications, and maintenance programmers working on new or legacy code written in the REXX language. It describes the REXX programming language for TSO, MVS, OS/390 and Z/OS. (IBM mainframe operating system environments). The book quickly gets you writing programs in REXX. It covers all REXX language elements, all REXX built-in functions, and the more important TSO-only functions. You will find URLs in the book linking to a set of practice problems on a public webpage, as well as additional information on setting up your TSO session to execute REXX programs. This book was written and published in 2012 by the author of "REXX in the TSO Environment." The REXX Language on TSO improves on "REXX in the TSO Environment" in every way: it clarifies important points; it is better organized, and gives better examples. REXX is a high-level scripting language created in the 1980's by IBM for the IBM mainframe operating systems CMS and MVS. It quickly gained popularity and expanded into other environments such as Netview, CICS, AIX, QMF, VSE and OS/2. REXX is often used for prototyping applications, front-ending operating system commands and TSO/ISPF panel applications. Its flexibility and clear straightforward syntax makes it a welcome replacement for IBM utility programs. REXX is generally not used for high-volume business applications because of its performance limitations with respect to compiled or assembled languages. REXX is able to read and write sequential files and/or PDS members. It contains all programming language features, including the ability to do calculations with decimal numbers to any precision. It is especially useful in manipulating character strings in free-column format. There is a chapter containing examples of REXX programs, macros, and user-written functions. Explanations of the code are shown on the facing page.

"Essential Techniques for Rexx Programming" "Essential Techniques for Rexx Programming" is a comprehensive guide to mastering Rexx, an influential scripting language renowned for its simplicity and power on both mainframe and modern platforms. The book opens with a thoughtful exploration of Rexx's historical roots and language architecture, laying a solid foundation with deep dives into its lexical structure, data representation, modularity, and memory management. This approach equips the reader not only to understand the rationale behind Rexx but to adopt best practices for building robust, scalable programs. Seamlessly bridging theory and application, the subsequent chapters tackle the full spectrum of procedural techniques, advanced string and data manipulation, and sophisticated system interfacing. Readers gain practical insight into control structures, exception handling, dynamic data structures, and high-performance data processing. Dedicated sections unravel how Rexx interacts with the operating system, detailing efficient file handling, automation, inter-process communication, and integration with both legacy and modern architectures. Extending Rexx's capabilities, the book demystifies user-defined functions, external libraries, and dynamic linking for scalable software development. Commitment to excellence is further evident in the comprehensive coverage of debugging, automated testing, performance profiling, and rigorous security practices essential for professional-grade scripts. The closing chapters delve into real-world patterns and case studies, including serverless architectures and modernization of legacy code, while also surveying the open-source landscape and future directions for Rexx. Rich in detail and organized for clarity, this reference is an indispensable resource for developers, architects, and technical leaders aspiring to leverage Rexx's full potential in contemporary and evolving computing environments.

The REXX programming language includes built-in functions that simplify programming. REXX Functions let you manipulate data strings or do mathematics simply with a minimum of programming effort. This book explains 72 REXX functions that you can use in your REXX programs. This book is about TSO REXX functions, but we have included a few that work in CMS only. A function is a built-in feature of the REXX language. Functions are always available to you when you are writing your program. They provide an easy way to manipulate data strings or to perform arithmetic on numbers. Using functions simplifies programming and provides reliability, because the functions were created and tested by the software manufacturer (IBM.)The Index is not like most indexes that list only language features alphabetically. They are no help if you don't know the name of the language feature. This index shows the common English language name for a feature, for example, "Convert decimal number" points you to the REXX equivalent D2C. You don't have to know that D2C means "Convert decimal number to character" in order to use the index.The examples are simple and clear and will show you the different ways to invoke, or use REXX functions in a REXX program.To aid you in finding the function that you need, one chapter is devoted to listing the functions, classified by what they do. Each of the built-in functions is shown in detail with examples of use. The functions are shown alphabetically.As a bonus, I've included several supplementary chapters to make life easier for the REXX programmer:1. How to write REXX macros.2. Compatibility Issues across platforms.3. Precedence of Operators. What REXX processes first, in complex expressions?4. How to execute TSO Commands, in Native Mode (Ready Mode) TSO, in ISPF Option 6, on the command line on ISPF panels, and in batch.5. How to specify Dataset names in TSO commands. An explanation of TSO naming conventions.6. Finally, the TSO commands that you are likely to use in your REXX programs, arranged by their function, with clear and simple examples.

A major goal of operating systems is to process jobs while making the best use of system resources. Thus, one way of viewing operating systems is as resource managers. Before job processing, operating systems reserve input and output resources for jobs. During job processing, operating systems manage resources such as processors and storage. After job processing, operating systems free all resources used by the completed jobs, making the resources available to other jobs. This process is called resource management. There is more to the processing of jobs than the managing of resources needed by the jobs. At any instant, a number of jobs can be in various stages of preparation, processing, and post-processing activity. To use resources efficiently, operating systems divide jobs into parts. They distribute the parts of jobs to queues to wait for needed resources. Keeping track of where things are and routing work from queue to queue is called workflow management, and is a major function of any operating system. JES3 considers job priorities, device and processor alternatives, and installation-specified preferences in preparing jobs for processing job output. This IBM® Redbooks® publication describes a JES3 environment that includes the following: - Single-system image - Workload balancing - Availability - Control flexibility - Physical planning flexibility.
