About External Variables

You can use CA JCLCheck to validate JCL that contains external variables. This validation is required when a scheduling product uses variables embedded in its JCL. When validating JCL that contains external variables, the following steps are required before JCL validation occurs:

  1. Specify the product that CA JCLCheck calls to resolve the external variables.
  2. Specify the product-specific parameters for external variable resolution in a data set. CA JCLCheck then calls the product and receives resolved JCL.

This section provides a process overview and explains the steps that are required to resolve external variables using the following methods:

CA JCLCheck can resolve external variables in the following scheduling products: CA WA CA 7 Edition (CA7), CA WA ESP Edition (ESP), Control-M (CTM), and Tivoli Workload Scheduler (TWS). This section also contains a description of the product-specific parameter files.
