If there's an EXIT in the loop, it's an unpleasant surprise - I then have to backtrack through the loop code to figure out what led to the EXIT . Complex loop code may require separate EXITs scattered throughout the loop, making maintenance, enhancement and debugging difficult.

836545I see, thanks.
I'm not sure, though, how can we apply it to the original problem, though my first immediate idea was also to change two loops into do while (which I didn't propose).
If it's not broken, fix it until it is.
