 position field value position_value is too large

    Facility: DEBUG, VMS Debugger

    Explanation: The value of the position specifier in the BLISS
    field reference is an incredibly large number, larger than the
    Debugger can handle. The value may be negative, which is also
    illegal.

    User Action: Change the value of the position specifier in the
    BLISS field reference to a smaller (or positive) value.
