z/OS REXX Programming Workshop

CODE: ZL1_ES52

LENGTH: 4.5 days

PRICE: £2,975.00

Description

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.

Objectives

  • 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

Audience

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

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
