( #3333=superdoc: print w/ replies, xml ) Need Help??

I always look at these golf challenges and think "I bet x would be shorter" but it rarely is. Anyway:
sub ruler { my($n,$r) = (int($_[0]+9)/10, ' '); $r .= sprintf"%10s",$_ for (1..$n); "$r\n" . '0123456789' x $n . "0\n"; }
The sprintf would save a few strokes in your code but nothing significant. I'll take your word for it that there is a column 0. ;-)

For shorter rulers I often use a sequence like this which fits on one line and is easy to count::
123456789_123456789_123456789_123456789_123456789_123456789_
