The error in p. that I reported earlier was the source of my graphics problem: all the rescaled graphics were offscreen.
As a workaround, (2 2 $ 0 1 2 3)&p."1"1 (1 2$4 4) works where (2 2 $ 0 1 2 3)&p."1 (1 2$4 4) fails. Henry Rich ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
