    DESCRIPTION
            "This data type indicates the validity and sign of the data
            in associated object instances which represent the absolute
            value of a high capacity numeric quantity.  Such an object
            may be represented with one or more object instances. An
            object of type HcValueStatus MUST be defined within the same
            structure as the object(s) representing the high capacity
            absolute value.

            If the associated object instance(s) representing the high
            capacity absolute value could not be accessed during the
            sampling interval, and is therefore invalid, then the
            associated HcValueStatus object will contain the value
            'valueNotAvailable(1)'.

            If the associated object instance(s) representing the high
            capacity absolute value are valid and actual value of the
            sample is greater than or equal to zero, then the associated
            HcValueStatus object will contain the value
            'valuePositive(2)'.

            If the associated object instance(s) representing the high
            capacity absolute value are valid and the actual value of
            the sample is less than zero, then the associated
            HcValueStatus object will contain the value
            'valueNegative(3)'.  The associated absolute value should be
            multiplied by -1 to obtain the true sample value."

            Gauge, or TimeTicks) may be sampled.

            Because SNMP access control is articulated entirely in terms
            of the contents of MIB views, no access control mechanism
            exists that can restrict the value of this object to
            identify only those objects that exist in a particular MIB
            view.  Because there is thus no acceptable means of
            restricting the read access that could be obtained through
            the alarm mechanism, the probe must only grant write access
            to this object in those views that have read access to all
            objects on the probe.

            If the associated hcAlarmVariable instance could not be
            obtained at the previous sample interval, then a delta
            sample is not possible, and the value of the associated
