I just realized the note I sent a while ago doesn't do what you want it to
do... you apparently are not looking to retrieve all of the field names, but
to retrieve all of the unique values of a particular field.

I am confused now... I'm not at all sure what you want to do. You could
certainly loop through the dbase and create an array of unique values, and
use that array to define classes on the fly (I assume you could do that)...
but that doesn't sound like what your after either.
