Thanks, everyone. My actual problem was a little more general in that a box might contain more than one column. Moreover, box might contain a rank-one vector (row vector versus column). But your code handled these quirks.
I gave up using the ; primitive because of the extra singleton axes.

That's like recommending a book you haven't read. Try running that line... By the way, Leigh, if you promise that table is a vector of at least two boxes, then you can shorten your verb a bit: ,.&:>/ table But the general case is much nicer with >@:(,.&.>/) which is faster and leaner anyway. -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
