Topic: command to clear a graphics screen?

Trying to get a small circle to grow as it moves across a graphics screen.  "call clearscreen" does not work.

You should be calling clearviewport to clear the window contents.  If you're double-buffering, though, you'll need to call swapbuffers as well, or it will appear that nothing is happening.
