"Exit repeat" exits only the loop that statement is in.

You can exit to handler with "exit <handlerName">, or exit all script 
execution with "exit to top".

But if you need to exit a specific repeat structure, you'll have to add 
an "exit repeat" for each level you want to exit.

At once of the RevCons a few years ago Robert Cailliau proposed adding 
an option to name repeats so we can exit any of them from any level. 
Might be nice to see that one day.
