This will make that happen.
@LOOP
LOCATE 0,0PRINT "First screen."
IF BUTTON(2) AND #B THEN CLS:GOTO @LOOP2
GOTO @LOOP
@LOOP
LOCATE 0,0PRINT "Second screen."
WAIT 200
Before your loop after the spsets type spcol 1:spcol 2
Then in your loop type IF SPHITSP(1,2) THEN BEEP
and that should work! :)
Also I added a circle shape function to artwork, look in my posts for key. :)
