I think you can stop a loop if you use BEGIN ... END syntax. Without it,
the loop is compiled into one command and is not interrupted until
finished; with it, each item inside is a separate command, so IDL will
check for breaks every time. I am not sure that it affects the speed at all.
Cheers,
Pavel
