Basic Subsystem (BSS)

Whether or not the MDBF option is used, the subsystem on which the TPF system programs and associated system records reside is designated as the basic subsystem, which is given the reserved name of BSS. This implies that the TPF system is IPLed and restarted from the basic subsystem. The basic subsystem can be declared with one or more subsystem users if the system is generated with MDBF.
