That would lengthen the solution. To compensate, you might consider that there's no reason to make the solution a stand-alone, assignable verb (which won't work with 1!:1]3 anwway). You could probably save some characters by using an immex expression instead (i.e. skip the @ and the [: and all that). -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
