loop -- marks the end of an infinite loop

do 
  ... 
loop 

The loop-command marks the ends of a loop (which is started by do), wherein all statements within the loop are repeated forever. In this respect the do loop-loop is infinite, however, you may leave it anytime via break or goto.

print "Hello, I will throw dice, until I get a 2 ..." 
do 
	r=int(rand(6))+1 
	print r 
	if (r=2) break
