Thank you for the help but the documentation for using an OGR VRT file 
does not seem to be clear.  I created a ovf file (see below) and ran
# ogr2ogr -f "ESRI Shapefile" thick18.shp thick18.cvs
but still no change only a dbf file is created.  I do not see in the VRT 
documentation how to use the ovf file.
