CICS TS – Programming Basics 5.6


6 hours


The CICS TS – CICS Programming Basics course provides an overview of the CICS Transaction Server product and describes how it is used to process work. It looks at the application code required for programs working with CICS, using various programming languages. It also describes the major interfaces used to interact with this product.


Application programmers requiring introductory knowledge about the concepts of the CICS Transaction Server, and how it can be used to deliver legacy and newer, web-based solutions.


Completion of the following Interskill course, or equivalent knowledge:

  • IBM (z/OS) – Introduction to the IBM Enterprise Environment
  • Ability to program in at least one mainframe programming language


After completing this course, the student will be able to:

  • Describe the CICS environment and how transactions are used to process work
  • Identify how CICS programs are prepared for execution
  • Describe how commands are used to request CICS services
  • Identify interfaces that can provide access to CICS
  • Describe how Java programs are coded to run in CICS, and use CICS services
