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.

"NetRexx is a new human-oriented programming language, designed as an effective and simple alternative to the Java language. With NetRexx, you can create programs and applets for the Java environment faster and more easily than by programming in Java. Using and writing Java classes is especially easy in NetRexx, as the different types of numbers and strings that Java expects are handled automatically by the language." "Inspired by two very different programming languages, Rexx and Java, NetRexx blends the easy-to-learn syntax of Rexx with the robustness and portability of the Java environment. The result is a language which is tuned for both scripting and application development, and is therefore truly general-purpose." "In this book, Cowlishaw both introduces and defines the NetRexx language; these descriptions are complemented by a discussion of the key design principles of the language."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

In 1998 one programmer changed the world of Java. Frustrated by his efforts to create a cross-platform build of Tomcat using the build tools of the day (GNU Make, batch files, and shell scripts), James Duncan Davidson threw together his own build utility on an airplane flight from Europe to the U.S. Named Ant because it was a little thing that could build big things, James's quick-and-dirty solution to his own problem of creating a cross-platform build has evolved into what is perhaps the most widely used build management tool in Java environments.

This highly comprehensive handbook provides a substantial advance in the computation of elementary and special functions of mathematics, extending the function coverage of major programming languages well beyond their international standards, including full support for decimal floating-point arithmetic. Written with clarity and focusing on the C language, the work pays extensive attention to little-understood aspects of floating-point and integer arithmetic, and to software portability, as well as to important historical architectures. It extends support to a future 256-bit, floating-point format offering 70 decimal digits of precision. Select Topics and Features: references an exceptionally useful, author-maintained MathCW website, containing source code for the book’s software, compiled libraries for numerous systems, pre-built C compilers, and other related materials; offers a unique approach to covering mathematical-function computation using decimal arithmetic; provides extremely versatile appendices for interfaces to numerous other languages: Ada, C#, C++, Fortran, Java, and Pascal; presupposes only basic familiarity with computer programming in a common language, as well as early level algebra; supplies a library that readily adapts for existing scripting languages, with minimal effort; supports both binary and decimal arithmetic, in up to 10 different floating-point formats; covers a significant portion (with highly accurate implementations) of the U.S National Institute of Standards and Technology’s 10-year project to codify mathematical functions. This highly practical text/reference is an invaluable tool for advanced undergraduates, recording many lessons of the intermingled history of computer hardw are and software, numerical algorithms, and mathematics. In addition, professional numerical analysts and others will find the handbook of real interest and utility because it builds on research by the mathematical software community over the last four decades.

Thanks to the tireless efforts of open-source developers, Cocoon has quickly gained visibility as the preeminent XML-based Web publishing framework. Unfortunately, its documentation remains a significant shortcoming. If you're new to Cocoon, gaining a sense of exactly what you can do with it can be difficult, and actually getting started can be even harder. Cocoon 2 Programming: Web Publishing with XML and Java clearly explains the value of Cocoon and helps you build on your familiarity with XML and Java Servlets as you design, build, and implement a range of Cocoon applications. You'll begin by learning to control presentation for various platforms, both wired and wireless. Then you'll move on to Cocoon's capabilities for logic control and content management, using both sitemaps and XSP to create a site dynamically generated from a variety of data sources and types. As you'll see, Cocoon also supports powerful organizing techniques known as design patterns, and you'll master their use in both presentation and content generation. These are essential tools for the planning of your site; for after it's implemented, you'll command powerful techniques for site management and optimization. The Web's dependence on XML is growing rapidly--and with it the list of companies that have adopted Cocoon. Is Cocoon for you? Cocoon 2 Programming will guide you through your decision and far beyond, providing all the assistance you need to build a dynamic, XML-based site--and keep moving into the future.

Thousands of companies with IBM computers are looking for methods to make their systems Web compatible. This book, written by a team of IBM's leading developers, shows you how to use new Web gateway tools to connect existing applications to the Web, including DB2, CICS, and Lotus Notes.
