Reserved operand, encoded as floating overflow

    Facility: DEBUG, VMS Debugger

    Explanation: During a floating-point operation, a floating point
    value exceeded the largest representable value for that data
    type.

    User Action: Examine the code that caused the fault. Verify that
    the operands or variables are specified correctly. Verify that
    the encoded reserved operand was not deposited by a non-floating-
    point operation.
