Using OPS/REXX › OPS/REXX Overview

OPS/REXX Overview

A crucial part of the CA OPS/MVS product, OPS/REXX is a powerful, SAA‑compliant programming language that adds to standard REXX a set of extensions that automate and enhance the productivity of z/OS operations.

Because OPS/REXX differs only slightly from standard REXX, this chapter explains the differences between OPS/REXX and standard REXX instead of describing the REXX language completely.

Additional OPS/REXX and standard REXX documentation:

• For a list of OPS/REXX built-in functions that differ from and extend standard REXX, see the chapter “OPS/REXX Built-in Functions” in the Command and Function Reference.
• For more detailed information about standard REXX, consult the book THE REXX LANGUAGE: A Practical Approach to Programming by M.F. Cowlishaw. If you do not have a copy of this book, you can order one from Prentice Hall.

  Important! If you are not already familiar with REXX, see the Cowlishaw book before you read further in this chapter.

• You also may want to read Modern Programming Using Rexx by Robert P. O'Hara and David Roos Gomberg (Prentice Hall). This book includes many practical examples of REXX programming.
