Specifying the subsystem

To run Workload Automation Programming Language both batch and online, you must set the SUBSYS parameter to specify the subsystem used when the communication with HCL Workload Automation for Z was initialized.

When Workload Automation Programming Language finds a command that requires communication with the HCL Workload Automation for Z PIF, it automatically generates an INIT statement.
Note: Some OPTIONS keywords require communication with the HCL Workload Automation for Z PIF.

To communicate with more than one HCL Workload Automation for Z subsystem in a Workload Automation Programming Language session, you can initialize your own connection to HCL Workload Automation for Z by using an INIT statement before any other statement that requires the PIF.

SUBSYS is a required positional parameter, so even if you are specifying the subsystem explicitly using INIT statements, you must provide a value. The default in EQQYXJPX and EQQYXTSO is set to an asterisk (*) for this purpose.

You can also use the SUBSYS parameter to specify the default version to load at startup.
