(1)	Declaration of the SSD object.
(2)	Definition of the chief attributes of the SS1 subsystem: the entry points, references and dependencies.
(3)	Specification of the subsystems which must not share address space with SS1; in this example, these are the subsystems SS5, SS6 and SS9.
(4)	Specification of the holder task attributes of SS1, SS2 and SS3.
(5)	Saving of the SSD object containing the definition of subsystem SS1. In addition, the SSD object is saved to the ISAM file SYSSSC.SS1.001 specified under (1).
