MODE 1920,1080,8 : OFF
x = 0
REPEAT
    CIRCLE FILL x,1100,100
    x+=10
    Z=INKEY(10)
UNTIL x=3800

This simple code draws a filled circle across screen. Has anyone got a
routine I could add to make each new circle go through a gradual
colour change? Only very small and subtle changes of colour are
required to cover the whole of the RGB spectrum. Routine would need to
handle thousands of colours because each prime colour has 256 possible
levels.
