The computer language REXX is being used both to access databases and develop systems applications. This guide explains how to make REXX run under OS/2, offering a step-by-step approach which begins with basic concepts and examples to provide the reader with the knowledge required.

"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
