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.

Thanks,
