FSS(accccccc) - Functional Subsystem Definition

The FSS(accccccc) statement defines a functional subsystem to JES2. Use the FSS= keyword on the applicable device initialization statement to associate a JES2 device to a functional subsystem. Each FSS(accccccc) statement must have a unique functional subsystem name (subscript).

The subscript (accccccc) specifies the 1- to 8-character functional subsystem name. Each FSS(accccccc) statement must have a unique name. If more than one statement includes the same accccccc specification, all specifications on the last-defined FSS(accccccc) statement will override any previously defined.

The subscript can be a specific FSS name (for example, FSS2) or a more generic form such as PSF*, *, or a range of FSSs. See Subscript ranges for details.

If you modify FSS(accccccc) parameters and then restart JES2 with a hot start, JES2 uses the FSSs that were defined before JES2 termination.
