Hi everybody, bizarre question: I want to calculate with lingo the sunrise and the sundown on a given day at a given location on earth. I have bought a book that explains - tried to explain - how to do that in C++. I have no idea of C++ but I THOUGHT I would manage to convert that to Lingo but I was naive: It is FAR to complex and difficult. Has by any chance anyone ever tried to do that or is anybody out there expert in astronomy and lingo alike who could possibly help me understand that book? Is there a risk that even if I understood the subject this couldn't be done in Lingo anyway? Thank you very much Michael von Aichberger [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/LUJ/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]) Lingo-L is for learning and helping with programming Lingo.
