Interesting. Did not know that. I don't have a printer but the list of function names indicates this has something to do with geography. There is a NAD83 function, a SUN function, and a few other that seem to reference geology. When I ran NAD83 it asked for a zone. I gave it my NAD83 FIPS zone but it it didn't like that. Well, it might be fun to play with these and see if I can learn anything about them.
