CICS Command Level Programming



This course teaches CICS command level programming on CICS version 6.1. This course is also available at previous releases, please ask for details.


  • IBM CICS COBOL Programmers.
  • Batch COBOL Programmers moving into an IBM CICS environment.


Attendees should ideally have some experience of COBOL programming in a Batch


Upon completion, attendees will be able to:

  • Confidently code Command Level CICS Programs
  • Understand how to use File Control, Temporary Storage and Transient Data
  • Describe how to use time dependent commands, and how to link between programs
  • Understand how to deal with error conditions
  • Use CEDA to define their program to CICS and to use CEDF to test and debug their programs

An Introduction to CICS Web Services is included. Basic Mapping Support is included for 3270 screen design. The attendees will have access to a CICS/TS 6.1 System and will write a Command Level program, updating it to handle recovery and code a BMS map.
