Would anyone who solved this problem care to look at my solution (in the forum entry) and tell me of ways to speed it up! I looked at Oleg's solution but it is far too expert for my level! I am sure my version could be quickened up as other solvers have mentioned shortcuts but I can't see anything obvious. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
