Joe, I tried it and it seems neat.
On two screens I got 2 apparently equivalent, correct options: Transpose and Cut. On the Numbers question I did not get an option I liked, but there was one that looked likely `"".`. Also, I am not sure I like that when I get an incorrect answer, the retry is different from the original in the distractors. I have yet to look at the source, and that is where I hope to learn more. Thanks, -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
