> But I have a Array of Arrays there...

$elem is an array ref, you can also call it $a_ref or whatever explains best the content ($a_row for instance)

> How can I use join?

like shown, did you notice the @ in front of @$elem, it dereferences the array ref.

> Also, if you use foreach, doesn't it mean that you lose the order of elements?

Nope! Try it out...
