That's basically what I would do, but I would phrase that slightly differently: I=: [EMAIL PROTECTED] - 1+I.&.|. 0 2 2 5 I _5 1 2 3 9 0 _1 0 2 2 3 0 But beware of fonts which do not allow you to distinguish between I and | (or I. and |.). -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
