I realized, just now, that I quoted "quotes" with the wrong kind of quotes - " in J is not a quote character but something entirely different.
http://en.wikipedia.org/wiki/Rank_%28J_programming_language%29 If you want to quote a string in J, you'll need to use 'apostrophes' (and double them for embedded apostrophes, and a few other stunts for non-printing characters). Anyways, I hope that I wasn't leading you the wrong direction there.
