Drawing One Point Many Times

PSET sets a pixel at the designated column and row of the graphics screen. The pixel will be white unless the COLOR statement has been used to change the pen color.

Here is a program that draws the point at column 59 and row 103 ten thousand times:

SCREEN 12
FOR DOT = 1 to 10000
  LET X = 59
  LET Y = 103
  PSET( X, Y)
NEXT DOT
'
END

This is not a sensible program. Once a point has been drawn, drawing it over and over adds nothing. It would be nice to draw ten thousand different points.
