Is break broken? :) :) :)

[Brian T. Matchick]

I've started writing some expect scripts and have run into a little problem.
Mind you, I only have the O'Reilly Expect book, not Tcl, yet. :) Anyhow, I'm
trying to use break from within a nested loop (for inside a while) and
instead of
just exiting from in inner loop and moving on to the next command, it seems to
'continue' the outer while loop as well.

Is this right? Does break act funny with nested loops or should it work
just like
I'd think, just break out of the current loop (nested or not) and that's it?

Thanks for any info!

Brian

The simplest example I could think of works:

while 1 {
puts hello
for {} 1 {} {
puts there
break
}
puts again
break
}

If "break" forced a continue of the while loop, you'd get "hello there
hello again", but I get "hello there again", which is what I expected.
