Using variables

You can use user-defined variables, RUV-defined variables, and IBM defined variables when you create journal models, job JCL records (skeleton JCL), internal readers, and VSAM name models. You can use variables to set values for the following elements:

• Journal and job names
• Dates and times
• User and system identifications
• EXEC statement elements such as program, procedure, and step names

In addition, in backup and restore job JCL records, you can use action variables to control the variable substitution process.

During application program processing, RUV resolves variables to obtain data set names to use in allocation of log, journal, and backup data sets.

You create a user variable by defining the variable name and variable value with the ADD USER_VARIABLES statement, as explained in Creating User Variables.
