40 .frame
The F R A M E command synchronises the movement of objects on the screen to the
display frame scanning frequency. If that's a bit technical for you,just remember that
the command should be used whenever you want to move characters or graphics
around the screen smoothly.
This program can be further enhanced to improve the movement by adding some
delay loops and by using a different returning character symbol.
