i am retired.

i have written a shareware programs for my hobby .. ham radio.

you can see (or download) my program at my home-based website .. http://www.wa0h.com .. the (0) is the number zero.

i would like to add a day-night world map .. i just want to display the day-night regions for the current time.

i am hoping it is a simple algorithm.

if it is a simple module, can someone supply me with the source code, or refer me to a book that has the code outlined ?

i wrote my program in visual basic .. but i can decode most languages.

thanks for your time.
