Available in PDF, EPUB and Kindle. Book excerpt: Designed for those who want to study that intellectual, human activity called programming, this book introduces the REXX language. Both beginners and those experienced in programming will find REXX simple to learn and easy to use to achieve practical results. REXX combines the simplicity and immediacy of BASIC with the structure and power of languages such as PL/I and PASCAL. You will need only a basic familiarity with arithmetic to use this book in learning how to think in organized and constructive ways for problem solving. This book will help you to: think through a programming problem, refine the solution of the problem in successful steps, consider what must be achieved at each stage, create a program that will produce the intended result, learn how to verify and prove your programs correct and make them run faster when needed, use REXX easily and creatively as you become a competent programmer.
