layer definition at the bottom of this email.  I don't understand.  
Why do I need a filter?  What filter do I need?  I've read everything 
about this I could find before asking you, but the documentation on FILTER is 
very brief, and the mail archives didn't provide a solution.  I should 
point out that I'm using OGR MapInfo TAB data.</FONT></SPAN></DIV>
