We can provide tacit forms easily enough. For example: Set=: /:~...@~. sortSetR=: Set@($:&.>^:(*...@l.)) (sortSet -: sortSetR) 5!:2 <'sortSet' 1 But note that this assumes that if you are working with sets of sets, only level 0 items of arrays are anything other than sets. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
