Hi Michael,

I've come across .gpx files before and since they seam to mostly be text 
in xml format these are definitely useful if they include a text label in 
addition to the coordinates.

Perhaps someone else can comment on .arc files.

The format of Loadstone text files used for importation is pretty straight 
forward as you will see if you examine a file...

Name = quoted string describing point.
Latitude = decimal latitude (with 7 places to the right of the decimal) 
without the decimal point inserted.
Longitude = decimal longitude (with 7 places to the right of the decimal) 
without the decimal poin inserted.
Accuracy = gps accuracy at the time the point was saved (may be 0)
Satellites = satellites in view when point was saved (may be 0)
Priority = point attribute reserved for Loadstone (may be 0)
Userid = unique userid calculated from the userid string from the 
Loadstone/Settings screen.
ID = Unique numerical id for the point.
