Programming in BASIC on the Color Computer chapter 19 "Going in Circles"
9In chapter 19 we learn about the CIRCLE command, which can be used to create circles, arcs, and ellipses by changing some of the parameters you send to the command.
The simple syntax for the CIRCLE command would be CIRCLE (X,Y),RADIUS,COLOR
This would create a circle at a given X/Y coordinate with a given size and color.
You can add to the syntax by specifying the Height-to-width ratio to make the circle tall, flat, or wide, and you can specify the starting and beginning pieces of the circle to draw as well.
It's a pretty cool command and can be used in a lot of ways to add nice round graphics objects to any scene you want to create.
I ended up adding to to our graphical demo, so now that demo does pixels, lines, boxes, filled boxes and circles. As we learn more commands, we'll add them to the demo.
