floating point control registers can be accessed only in scope 0

    Facility: DEBUG, VMS Debugger

    Explanation: An attempt was made to reference a floating point
    control register from a scope other than scope 0. DEBUG will not
    accept a command which specifies any other scope for a floating
    point control register.

    User Action: If the current scope has been set to a scope other
    than scope 0 (using the SET SCOPE command), use an explicit
    0\pathname to access the floating point control register.
