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.

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
