Can I assume that an auto-increment operation on an integer value is atomic
(that is, cannot be interrupted by another thread)? This is a common
assumption in C/C++. The perl debugger I use leads me to believe that perl
stores all integers as strings however, in spite of my efforts to force them
to integer by adding zero.
This would mean that an auto-increment is probably not atomic.
What about a string copy: is that atomic?
Thanks,
Siegfried

How do I programmatically and gracefully exit a TK GUI program? I was
looking for a close function for MainWindow, but could find none.
Thanks,

Tk::exit;
or
exit;
Like
$mw->Button(-text=>'Exit', -command=>sub{exit})->pack();
