WHILE (r0) > 0 DO

Although it works the same in this particular case, in general, this isn't the same as

Code:

while True
# do something
if r0<=0:
  exit

Why? Suppose r0 =-4 when the code reaches the while statement. What will your loop do? What will mine do?

Yours isn't executed at all if r0 <=0. The example from the website and my example will execute the loop at least once.
