Startup procedures for subsystems

You must have two distinct procedures to start an XRF complex because there are two separate IMSsubsystems that perform different functions.

In an XRF complex, the OLDS definition (OLDSDEF) for the active subsystem must match the OLDSDEF for the alternate subsystem. Also, all OLDSs used by the active subsystem must be accessible to the alternate subsystem, regardless of whether they are in the OLDS definition.
