Now, well-known author "Dr. Batch File" offers a cutting-edge resource for writing advanced programs in REXX--the powerful, yet relatively unexplored programming language included with OS/2. This guidebook introduces REXX, explains how to write REXX programs of varying levels of sophistication, and even discusses how to debug REXX programs. Part of the IBM McGraw-Hill Series. Includes disk and illustrations.
This book/disk combination tells the growing number of OS/2 programmers and developers everything they need to know to use the WATCOM-VX-REXX language to create REXX programs that have a visual interface. Written with the full support of WATCOM, it's an essential guide for those who have purchased the VX-REXX program but need more "how to use it" information than the manual provides.
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.
REXX is one of the hottest development languages today. Now, with the practical step-by-step approach of this book, anyone can learn REXX. Programmers learn what they can do with REXX, where REXX fits in on OS/2, and how to create and execute a REXX program. Other topics includes REXX syntax, some simple REXX verbs, debugging, and much more.
Teach Yourself OS/2 Version 3 in a Week is a self-paced tutorial where each lesson builds on what was learnied previously. By spending only a few hours a day with the book and OS/2, the reader will quickly get up to speed with the operating system. This new edition adds coverage of OS/2 for Windows, multimedia, IBM Works, and the Internet interface.
This book/disk set focuses on memory management, optimizing, and customizing OS/2. Disk includes shareware and freeware utilities. Discusses how to improve the performance of Windows and DOS applications running under OS/2.
This one-of-a-kind book/disk combination gives the growing number of OS/2 users the information and file management utility programs they need to organize their files quickly and easily. Readers will learn how to increase productivity by streamlining the process of switching between active programs. The disk contains a complete version of OS/2Tree 1.3.
Designed to run 32-bit applications, IBM's OS/2 Version 2.0 was created to take full advantage of 386 and 486-based PCs and workstations. The book, written by an IBM insider, emphasizes the design issues of software development for OS/2 applications. It shows programmers how to squeeze the most from 32-bit systems--for dramatic increases in speed and power.
A comprehensive introduction to OS/2 2.0, for experienced PC users who are new to the OS/2 environment, and experienced OS/2 or Microsoft Windows users who want to upgrade to OS/2 2.0. It explains the structure of OS/2.0 and its graphical user interface; covers installation, customization, configuration, optimization, and networking; and contains a command reference covering all OS/2 prompt- level commands.
