The data is listed as Point #, Northing (y-coordinate), Easting (x-coordinate).
The beginning and ending points can be renumbered and described to differentiate them from their aliases. If a weight (option <0>) is assigned to the beginning and ending points, those points will be held and no best fit line will be calculated for them.
