If the cost of comparing $. to 10 is significant compared to the rest of your loop, you're in the wrong programming language. However, having said that: my $meat; $meat = sub { $meat = sub { real body of loop here } if $. >= 9; }; $meat->() while <>; There. Happy? No more tests. And now you'll complain about the subroutine call. :) -- Randal L.
