Thank you, Laurent_R. That definitely clears up how the %seen hash is doing its thing. The bit about the %word hash I already understood . . . It was just the use of $_ that threw me for a moment. If you have thoughts on the question asked at the beginning of the (edited) post, I'd appreciate that as well! Thanks very much for you've already written here.
