The SUBSYS option displays status and other information about all or selected operational MVS subsystems.
Subsystems (as defined in IBM systems) are groups of routines that act as extension of the operating system. Communication with these routines is established through specialized interface services designated as the Subsystem interface.
To obtain information about subsystems, type S (Select) to the left of the SUBSYS option in the Automation Options menu. The window shown in Figure 63 is opened.
