SUBSYS – Input file for controller options

Workload Automation Programming Language can read subsystem specific OPTIONS statements after it has read the default options from the OPTIONS input source. Use the SUBSYS keyword to specify the DD statement from which to read the subsystem specific options (the default is <blank>).

This keyword is effective only on OPTIONS statements contained within the OPTIONS input stream.

From version 3.4 and later, instead of using OPTIONS SUBSYS you can code subsystem specific statements at any point in the command stream, including EQQOPTS.

For example:
<global settings>
IF @V(ZSUBSYS) = “TWSA” THEN DO
<controller settings>
END
