ACK.
On second thought, for the case where ($counter % 40 == 0), we want 40 spaces if $counter is 0, but 0 spaces if $counter is positive. I think we need a slight tweak. Rather than:
+ len=`expr 40 - \( $counter % 40 \)`
how about:
if test $counter = 0; then len=40 else len=`expr 39 - \( \( $counter - 1 \) % 40 \)` fi
True, the current expression doesn't work for counter = 40. You're expression fixed this, but no reason for special casing 0 here, as modulo on negative values is perfectly fine and yields the right result here expr 39 - \( \( 0 - 1 \) % 40 \) is 40 ACK, to you're equation (but without special casing 0) as I already pushed my patch. -- Matthias Bolte http://photron.blogspot.com
