Use a variable, set the variable when you hit an exit criteria, then 
before repeating the loop, check the variable, if it's true, exit the 
loop (exit does this), or just craft the loop (easy to do if it's a loop 
until construct) so it exits the loop automatically.  Probably not as 
efficient as break, but since I didn't know it was a valid command, <shrug>
