Accessing raster vat attribute fields in the Raster calculator

Discussion created by cmh_twig on Oct 23, 2010
I want to access the "virtual grids" represented by the attribute fields in the vat in the raster calculator.  This of course was very easy & efficient in ArcView 3.3, but seems to be not very easy or is notw impossible in ArcGIS 9.3.1.  Any one have any success with this issue?
