Right... last will break me out of my loop... but why not just exit as soon as I've accomplished the purpose of the script instead of adding an extra command?

Update: Here's what I mean:
Adding the last statement would require an additional conditional: 
my $success;
for(@host){
  $stout = run($_);
  unless($stout == 256) {
    $success++;
    last;
  }
  print "$_ not responding, trying next host\n";
}
print "all hosts not responding" unless $success;

    Indeed, no reason why you should not use exit to kill the program if you're done. I was just pointing to the side-effects of exit: you may get more more than you bargained for.
