chr gives the character corresponding to an ASCII value. 65 = 'A', 66 = 'B', and so on. In retrospect, I could have made my loop 65..90, but I think 1..26 makes it more obvious that I'm spanning the alphabet. Putting x4 after it just turns 'A' into 'AAAA' and so on, to make it more obvious that they're words.
