I've been wishing for a built-in way to do that. Maybe later. For now, you can use a conjunction (which takes a method name as a left argument and an object list as a right argument) which produces the desired verb. eachObj=:2 :0 ((<m),each '_',each n,each '_')`:0 ) Thus, if stacks is a list of stack objects all of which have the pop method: 'pop' eachObj stacks '' -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
