Christy,
Add two columns to your table to store latitude and longitude (if you don't
already have them) and update them. Save a copy of your table. Open the new
table and go to "Table -> Maintenance -> Table Structure" and click on the
"Table is Mappable" box to remove the points that are associated with the
table. Go to "Table -> Maintenance -> Table Structure" again and click on
the "Table is Mappable" so that new objects can be linked with the data
records. Then enter the following in the MapBasic window (assuming your
table is called NEWTABLE, the fields that contain the latitude and longitude
are LAT and LON and you want the radius to be 25 miles):
Update NEWTABLE Set obj = CreateCircle(LON, LAT, 25)
