The following program MERCATOR calculates the course direction and distance in miles given two pairs of latitude (north/south) and longitude (east/west). Conversion to arc minutes will be required during calculation.

Very interesting and useful program. Do you think it could be implemented in HP 67 and/or HP 35s?
