    Looks very interesting, Lars, and must represent a huge amount of work.
    a few queries:
    Will it run on Macintosh computers?
    Is it independant of the correct GMT being displayed on the computer's
    clock? Mine is decidedly inaccurate, although it is regularly updated to
    this local time. Can the relevant local time only, with the appropriate
    correction, be used?
    I enjoy solving (or not) the navigational problems such as the 'Silicon
    Sea' series on the Nav. list. These can involve data from all over the
    world and any time zone, and any year. My own approach is to always
    start with local time and convert to GMT when necessary. Could your
    program cope with these parameters? For example, I note that the almanac
    is good for the next 10 years but how far back does it go?
    Your example shows an assumed postion in whole degrees. How would it
    cope with a DR position that may involve one tenths of a minute of long.
    or lat. ? (Personally I think that a DR to the nearest minute is all
    that is needed or practical but the problem being worked on may use
    greater precision)
