Re: DMS v. decimalized degrees

I don't believe the Basic programs for the C-64 had a built-in DMS
conversion - you had to write your own. However, my Sharp PC-1211
"pocket computer" from that era did and proved to be an invaluable tool
for analyzing some ninetenth century surveys in the Pacific Northwest.

To add to the confusion, the Army at that time used degrees - minutes -
and decimalized seconds. The Navy (to be different) used degrees -
minutes - seconds - thirds (1/60 sec) for Latitude and hours (15 deg) -
minutes etc. for Longitude. It is not surprising that we remained
undiscovered for so long!
