My reading of the J FSM is that it can only refer to the current row. I hope I'm wrong... but perhaps sometimes you just have to have a loop.
It's a bit like "3 <\ 'abcdefgh'" without a different verb instead of '<' and for a higher rank than 1. Perhaps it is achievable this way as well. Oh, but it must have a memory so "3 <\ 'abcdefgh'" wont work. --Steven ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
