layer definition at the bottom of this email.&nbsp; I don't understand.&nbsp;

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.&nbsp; I should 

point out that I'm using OGR&nbsp;MapInfo TAB data.</FONT></SPAN></DIV>
