Overview

This course is designed to teach you the basic skills required to write programs using the REXX language in z/OS. The course covers the TSO extensions to REXX and interaction with other environments such as the MVS console, running REXX in batch jobs, and compiling REXX.

Prerequisites

You should be able to:

  • Code basic Job Control Language statements
  • Code in a programming language
  • Create, alter, and delete data sets using TSO

These skills can be developed by taking:

  • Fundamental System Skills of z/OS (ES10)
  • A programming language course
  • Write programs using the Rexx language
  • Use various data parsing techniques
  • Use built-in Rexx functions
  • Create user-defined internal and external functions and subroutines
  • Issue host commands from within Rexx execs
  • Code programs that read and write data sets
  • Use instructions and commands that manipulate the data stack
  • Use Rexx debugging tools
  • Write error-handling routines
