Conceptually speaking, append and laminate join items. And if the items aren't quite the same size then the fill rules can be used to make them (the items) have the same structure. However, stitch works "within" items. It pairs up items from each argument and dives into them to pair up their contents. Anyways, if you want "stitch with fill", you should probably use ,./@,: 1 2 3 ,./@,: 4 5 1 4 2 5 3 0 But notice how the fill rules conflict with stitche's definition: (i.2 3),. 6 7 0 1 2 6 3 4 5 7 (i.2 3),./@,: 6 7 0 1 2 6 7 0 3 4 5 0 0 0 -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
