Once upon a time, 11-Aug-01 13:49:28, Andrew Bruno spoke thus about
'[arexx] Back to my "ITERATE" problem':

If you're trying to terminate the loop when you've found a match then you
should be using LEAVE or BREAK depending on your circumstances.

ITERATE causes the next iteration of the loop, (ie. simply put, returns
script flow back to the previous DO command).
