OPC call to get EU descriptor text from IN_SCALE or OUT_SCALE

What  is the proper parameter reference that will return the engineering units text (not the lookup table number) for either IN_SCALE or OUT_SCALE? We have tried OUT_SCALE.UNITS and that returns an integer value.

    By my personnal experience, it is not possible to get the unit scale text - only an integer that may represents an index in the units words table.

    Yes, it is disappointing, I know ...
