if-then on single line fails

$r = 0
While 1
	 $r+=1
	  if $r > 10 then ContinueLoop
WEnd

This code fails with this error:
==> "ContinueLoop" statement with no matching "While", "Do" or "For" statement.:


I saw that it doesn't work because the ContinueLoop is on the same line of the if-then.  Why I can't put it on the same line?
