z/OS REXX Programming Workshop

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

Issues

Writing programs using the Rexx language
Using various data analysis techniques
Using Rexx’s built-in functions
Create user-defined internal and external functions and subroutines
Issuing host commands from within Rexx executables
Coding programs that read and write data sets
Using instructions and commands that manipulate the data stack
Using Rexx debugging tools
Writing error handling procedures

Who is this training for?

This is an intermediate course designed for people who need to write and maintain Rexx programs in a z/OS system environment

Prerequisites

Encode basic Job Control Language instructions
Code in a programming language
Create, change and delete data sets using TSO
