The program uses longevity and latitude from a commercial zip
code database. It calculates the great circle distance between two sets
of coordinates. The supplied coordinates could be wrong for Dorset or
Rutland. Do the airline distances to the other locations seem
I'm not sure how the database determines the coordinates for
a specific zip, I would hope they are for the geographic center of
the zip code but I don't know.
If anyone is interested in this program contact me off list.
I have a version of this program that will display the distance from
a given zip code to all the countries and the great distance for any
country in the world.

Joe is your computer still for sale? I've send you a couple
of email but
one of us may be getting caught in a filter.
