(1)	Specification of the catalog whose contents are to be modified.
(2)	Addition of a subsystem definition contained in an SSD object.
(3)	Addition of a subsystem definition that was written in the old DSSMGEN syntax (UGEN format).
(4)-(6)	Addition of a new subsystem and specification of its attributes.
(7)	Deletion of a subsystem definition from the catalog.
(8)	Modification of a subsystem definition which has already been entered in the catalog.
(9)	Removal of the strict address space separation on both subsystems.
(10)	Modification of the work task attributes of a subsystem which is being used as a work task.
(11)	Performance of a catalog check.
(12)	Saving of the modified static subsystem catalog.
