One-Line Bouncing Ball: Commodore 64 BASIC
Besides the famous 10 PRINT, one of my favourite type-in programs from the Commodore 64 User's Guide is "More Bouncing Balls" in which a ball bounces off the borders of the screen. Inspired by Josip Retro Bits' 2-line version of this program, I attempt to squeeze it down to one line, with some other diversions along the way.
