Parameters - zOS

Displays a list of parameters that will be inserted into the JCL. Each parameter consists of a Name and a Value. You can enter as many parameters as needed.

To add a parameter, click the + icon; add a Name and Value, and click the Update button. To delete a parameter, click the parameter on the list, the - icon, and the Update button.

Each parameter that you enter creates a separate JCL construct called the SET command. Each one appears as a new line inserted dynamically into the JCL submitted to the Controller for the current execution. The JCL is not permanently modified.

For example, you might specify a parameter Name = RUNTYPE and Value = PROD. This results in the following JCL SET statement being inserted in the job after the job card:

// SET RUNTYPE=PROD

The Parameter fields also support two additional special functions:

• They allow you to specify any steps you want skipped during the job run. See Skipping Steps during Initial Run for detailed instructions.
• They allow you to add data to DD* input streams. See Using Variables in JCL and In-Stream Data Sets for detailed instructions.
