Two ways depending on the complexity of the polygon(s) in the polygon table.
1. use the SQL select
Select * from PointsTable Where obj Not Within (Select obj From PolyTable)
2. Add a column using table > update Column and add a temporary column to
the points table, get the data from the polygon table, using a join where
the obj in the points table is within the obj of the polygon table. The
value you add is a gield in the polygon table like name. You can then
simply select records in the popints table where the name field is blank.
(his is more useful when you wish to select points that are not within
particular categories.
