I was trying assorted plots with my 2068 when I noticed that one of them looked like part of the rings of Saturn. At that moment I ttought, “Why not write a program that draws Saturn?” After a little playing around, I decided it needed to have Cassini’s division. A solid ring did not look like the Voyager photos, so Z$ was needed. Z$ instructs the program what to plot and what to leave blank. The print statement keeps stars from showing under the planet and shadow the rings to give a view that can’t be seen from Earth. To get the printer copy to show black sky, the screen had to be filled up and then the INVERSE command was used.
Run the program and press any key when you have enough stars. Saturn will then be drawn. Impress your friends with the graphics on your 2068; run Saturn!
