radix override not allowed with BLISS fields

    Facility: DEBUG, VMS Debugger

    Explanation: The use of a radix override qualifier is not
    supported when evaluating a BLISS field reference. BLISS field
    references are always displayed using a decimal notation. It is,
    however, possible to use a radix override qualifier when refering
    to the contents of a BLISS field.

    User Action: Don't use a radix switch with a BLISS field.
