Algorithm from June 84 QST page 56
Calculation section by WS4G and SM0CCM
If any errors are found please send the information to N4TL
Sunrise and Sunset Program. Useful for radio communications."
This program will calculate the sunrise, sunset, and length
of the day for all the countries listed in the SUN.DAT
file, or for a single location. the SUN.DAT file has
to be on the same disk as the default disk.
Times are in hours and minutes UTC.
When the file input is used the times are calculated and
displayed on the screen. The times are saved in the program,
and can be sorted and printed.
Compressed print can be used (for the IBM Graphics Printer).
If the SUN.DAT file is edited its format has to remain
unchanged. It also has to be saved without compressed
characters. If the Personal editor is used, use the NOTABS
option when saving the file. The maximum number of countries
is 500.
