VTPONG, VIDEO TERMINAL PONG
 
 
 
 
 
ABSTRACT:
 
	If you play PONG on your TV, you'll like VTPONG on a terminal
 
screen.  You put the index and middle fingers of one hand sideways on 
 
the keyboard to move your paddle up and down;  your opponent does the
 
same.  Moving both fingers one adjacent key closer to keyboard center
 
jumps the paddle four steps instead of one.  There are beeps, too:
 
one for bounce, two for serve, and three for miss.  Block digit scoring,
 
right or left "wall", and selectable paddle size and ball speed are
 
also featured.
