Actually, that was perfect.  I did not know that the cats file did not
automatically get created and now know how to create one.  I have now
done this successfully but have another question.  I guess this is more
of a performance question now but here goes:

I have now a map layer that has 43,000+  categories and it takes over a
minute to load up the cats when I do a d.what.vect.  

Is this what most people get?  

Am I trying to do too much with this tiger line import cats file to
query it for street names?
