You are close. You will find the missing pieces for your code in perlfunc, there specially open, readline, close. For swapping the first words in a line look for the word 'swap' in perlre. See perlsyn for control structures.

I have a dog, and he takes orders as spoken. It's only a matter of how I formulate them. That's how I call him: "fido, come or don't!"

And he comes, or doesn't.

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /

");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
