JCL (z/OS) – Controlling Job and Step Processing 2.5


3 hours



While JCL is generally rigid in the way that it runs programs and related jobs, in recent years there have been several advancements in code that can be used to conditionally run steps, and schedule jobs. This course discusses the use of the traditional COND parameter to control step processing, and the use of the IF/THEN/ELSE/ENDIF construct as an alternative. New basic job scheduling capabilities are also discussed.


Operators and programmers who need to know how to code and submit JCL batch jobs.


Completion of the following courses:

  • JCL (z/OS) – JCL Coding Basics – JOB and EXEC Statements
  • JCL (z/OS) – JCL Coding Basics – DD Statements

or equivalent knowledge.


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

  • Code the statements and parameters used to define a job group
  • Describe how COND parameters and IF/THEN/ELSE/ENDIF constructs are used to conditionally run job steps
