This small example will use the DO…LOOP
keywords to implement an endless loop, and the command EXIT
to break a loop. The outer loop will change, at each half of second, the border's color from black to yellow. The inner loop will change the color of border to red. Instead of continuing with the inner loop, this one will be exited by using the EXIT
command. The border color is changed using the COLOR BORDER
instruction, using the predefined constants YELLOW
, BLACK
and RED
. To wait for a specific amount of time the WAIT
command will be used, with the MS
(milliseconds) unit of time.
CLS DO COLOR BORDER YELLOW HOME: PRINT "YELLOW" WAIT 500 MS COLOR BORDER BLACK HOME: PRINT "BLACK " WAIT 500 MS DO COLOR BORDER RED HOME: PRINT "RED " WAIT 1000 MS EXIT REM The border will never be green! COLOR BORDER GREEN HOME: PRINT "GREEN " WAIT 1000 MS LOOP LOOP
