keyboard command to break out of infinite loop?

[BartlebyScrivener]

Thank you, Scott. I'm still learning my exceptions (obviously, or I
wouldn't get stuck in a while loop ;).

That was instructive. On my machine, it is Ctrl + Break that does it.
Ctrl + C doesn't do anything.

What I should really do is figure out roughly how many times the while
loop should run, and then put an outer limit on it, so that it will run
normally as long as it doesn't exceed x, after which it breaks and
says, "Hey, Dummy, you were headed into an infinite loop."

Could be a good exercise.

Thank you again.
