Course Summary:
This hands on, workshop-oriented course is intended for analysts, application and system programmers, system administrators, and technical support personnel who have a need to write, understand, or maintain REXX programs. This course applies to the z/VM-CMS, z/OS-TSO, and NetView environments.

Target Audience:
Analysts, application and system programmers, system administrators, and technical support personnel who have a need to write, understand, or maintain REXX programs.

Recommended Prerequisites:
No previous programming experience or programming training (in any language) is necessary. Delegates from z/OS sites will need the ability to create and modify files using the ISPF editor. For delegates from a z/VM environment, the ability to create and modify files using the XEDIT editor is required.

Course Objectives:
After completing this course, the student should be able to:

  • Code REXX instructions with proper syntax
  • Construct program logic using REXX control flow instructions
  • Define and manipulate user variables in REXX programs
  • Invoke and pass parameters to REXX programs
  • Code REXX instructions to accomplish file and terminal I/O
  • Describe the purpose and use of the data stack
  • Use REXX built-in functions to manipulate data
  • Create user defined functions and subroutines
  • Code REXX instructions that parse complex data strings
  • Debug REXX programs using the REXX TRACE facility
  • Identify the use of REXX command environments
  • Use REXX coding techniques which enhance efficiency and readability

    Key Topics:

  • Historical Background of the REXX language
  • REXX’s position in Systems Application Architecture (SAA)
