Hi Raul, yes it is algorithmic. When I say look back, I mean "look back in time". I think that "look-back" gets used in a few different contexts. Sorry for the confusion.
a simple example. 1 2 3 <-- FSM refers to back to entry 1 4 5 ... FSM steps forward ... 1 2 3 4 <-- FSM refers to back to entry 2 5 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. Thanks for looking! --Steven ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
