Book Synopsis

About This Book

Instant productivity increases are guaranteed with this book. It shows how to use REXX with TSO, the ISPF Dialogue Manager, the ISPF Editor, Netview, DB2, SQL, and the QMF forms panels. Long on practice (short on theory), this tutorial uses interactive examples to show how to use REXX and build a library of useful EXECS and MACROS. It covers REXX in TSO, OS/2, VM, and CMS environments.

The revised edition provides more detailed information on how to get the most out of the ISPF Dialogue Manager, and includes a comprehensive quick reference guide as an appendix.

REXX: Tools and Techniques by Barry K. Nirmal. "In this book, Barry Nirmal presents a whole host of utilities that form a ready-made compendium of software to help and assist the reader and his or her colleagues in their work and to offer them an in-depth knowledge of the routines' internal workings, making it relatively simple to adapt and tailor them to the needs of individual installations.

"This book provides the programmer with ready-made solutions to real-life problems and the framework upon which to build more complex and installation-dependent routines. Everyone will find something here, whether they are after an 'off-the-shelf' solution or the seed of an idea that they can develop into something much more sophisticated."— Steve Piggott, Editor, MVS Update
