What they do is *alias* $_ to whatever they're looping on. Try: sub foo { print } for (<STDIN>) { foo } As opposed to: sub foo { print } my $_; for (<STDIN>) { foo } ) Is this expected behavior? Yes. for() aliases whereas while() assigns. SaSW, Willem -- Disclaimer: I am in no way responsible for any of the statements made in the above text. For all I know I might be drugged or something..
