Distance between UTM zones

I am trying to write a distance meter using GPS. I have run into a problem when the beginning location and ending location go across the UTM zone. Is there a feature in Basic4ppc that can resolve this or some elaborate calculations are necessary.

Thanks in advance

Jerry

You could calculate the distance between two Lat / Lon coordinates instead of UTM coordinates.
The calculations are more complex, but it allows you to calculate the distance between any coordinates.
See GPS4PPC source code as it includes these calculations:
