Also, a frequently used idiom in J is (#~ predicate) collection For example: (#~ 0=2&|) i. 11 0 2 4 6 8 10 J does not really need hooks, for its expressiveness, but this one is nice and I see it and use it often enough that I think it is worth mentioning here. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
