I've been working through the weekend because of a deadline and I guess I'm a bit tired. The problem is this, for example you have the following data: [a=. i. 5 3 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 [b=. 3 + i. 2 3 3 4 5 6 7 8 What I'm trying to find is which rows in a matches b. I know I've done this before but for the life of me, I can't seem to remember how I did it. Guess need to get more sleep. I appreciate any help. :) Thanks. r/Alex ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
