Dear Listers, May be a rather simple problem, but I am going around for days... I have a table in MI 4.5. The first columns has categories (A,B,C,D) the = next columns have coordinates X,Y (Lat, Long). At the same coordinates, = may be different categories (in separate records). I wish to select a = given category. Easy. I wish to select everything but a given category. = Not so easy, because records without the category may fall into a = coordinate where the category I wish to exclude has been already found = (and listed in a different record). Some help? Thanks and best wishes, Agustin _______________________ Prof. A. Estrada-Pena Dept. of Parasitology Vet.
