FWIW, the DOC that you downloaded came from this site:
http://www.geocities.com/eentweedrievier2000/index.html
It freaked me out too when I tried it and it worked, but on closer inspection it appear that (in Firefox, at least) entering a text string in the URL bar is the same as entering the text in Google and clicking "I'm Feeling Lucky". Try typing "Quoth the Raven", and you'll get taken to an Edgar Allen Poe site.
I don't know what it has to do with codes or anything, but I believe the passage was written by Howard Carter, about when he first entered the tomb of Tutankhamen.
