This book provides a REXX tutorial combined with practical tips on programming methods and application development. Includes practical coverage of: programming for good performance; effective debugging techniques; user interface design strategies; system dependencies and interfaces; program maintenance guidelines; REXX interpreter and compiler implementations.

Originally developed for mainframes but highly portable across platforms-from servers to desktops to handhelds-Rexx is an easy yet powerful scripting language that's widely used for rapid application development. Covers Rexx interpreters for specialized functions-object-oriented, mainframe, and handheld. There are 8 different free Rexx interpreters optimized for different platforms and uses. This book shows how to use them all. Shows how to script for GUIs, databases, web servers, XML, and other interfaces. Details how to make the best use of Rexx tools and interfaces, with examples for both Linux and Windows. Includes a tutorial with lots of examples to help people get up and running.

This is still the best book we've seen for learning how to use the TSO commands that underlie ISPF. It is also an efficient introduction to CLIST and REXX.

&Quot;Whether you're new to Rexx or are an experienced Rexx programmer, this comprehensive reference offers you what you need to know in order to work with this easy yet powerful scripting language on any level. After a quick overview of the basics of Rexx, you'll move on to more advanced scripting topics such as portable code and optimal coding style.". "This book is for programmers on any platform who are either looking to learn Rexx or already use it and want to expand their knowledge of Rexx. A basic knowledge of programming is assumed."--BOOK JACKET.

This Nutshell Handbook® is a thorough introduction to the Korn shell, both as a user interface and as a programming language.The Korn shell, like the C and Bourne shells, is a program that interprets UNIX commands. It has many features that aren't found in other shells, including command history (the ability to recall and edit previous commands). The Korn shell is also faster; several of its features allow you to write programs that execute more quickly than their Bourne or C shell equivalents.This book provides a clear and concise explanation of the Korn shell's features. It explains ksh string operations, co-processes, signals and signal handling, and one of the worst "dark corners" of shell programming: command-line interpretation. It does this by introducing simple real-life examples and then adding options and complexity in later chapters, illustrating the way real-world script development generally proceeds. An additional (and unique) programming aid, a Korn shell debugger (kshdb), is also included.Learning the Korn Shell is an ideal resource for many UNIX users and programmers, including software developers who want to "prototype" their designs, system administrators who want to write tools for their own use, and even novices who just want to use some of ksh's more advanced interactive features.

The Handbook of Software for Engineers and Scientists is a single-volume, ready reference for the practicing engineer and scientist in industry, government, and academia as well as the novice computer user. It provides the most up-to-date information in a variety of areas such as common platforms and operating systems, applications programs, networking, and many other problem-solving tools necessary to effectively use computers on a daily basis. Specific platforms and environments thoroughly discussed include MS-DOS®, Microsoft® WindowsTM, the Macintosh® and its various systems, UNIXTM, DEC VAXTM, IBM® mainframes, OS/2®, WindowsTM NT, and NeXTSTEPTM. Word processing, desktop publishing, spreadsheets, databases, integrated packages, computer presentation systems, groupware, and a number of useful utilities are also covered. Several extensive sections in the book are devoted to mathematical and statistical software. Information is provided on circuits and control simulation programs, finite element tools, and solid modeling tools.

The z/OS System Logger is a function provided by the operating system to exploiters running on z/OS. The number of exploiters of this component is increasing, as is its importance in relation to system performance and availability. This IBM Redbooks document provides system programmers with a solid understanding of the System Logger component and guidance about how it should be set up for optimum performance with each of the exploiters. System Logger is an MVS component that provides a logging facility for applications running in a single-system or multi-system sysplex. The advantage of using System Logger is that the responsibility for tasks such as saving the log data (with the requested persistence), retrieving the data (potentially from any system in the sysplex), archiving the data, and expiring the data is removed from the creator of the log records. In addition, Logger provides the ability to have a single, merged, log, containing log data from multiple instances of an application within the sysplex.
