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 IBM Z Workload Scheduler was initialized.

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

To communicate with more than one IBM Z Workload Scheduler subsystem in a Workload Automation Programming Language session, you can initialize your own connection to IBM Z Workload Scheduler 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.
