This program - astron2 for dos is freeware.
You may do what you like with it but may not sell it.
This program will calculate the equatorial and horizon
coordinates for the five naked eye planets.
The results are close enough for an equatorial telescope
(about .25 degrees).
There is no error handling procedures written into the program,
so if you enter garbage you get garbage.
