The Dictionary seems to imply that 4 I. 5 6 7 should return 1 1 1 My reading of it is that in this case it should be applied to 0-cells of y and for each cell it should return #x, since x has no items, and #4 is 1.
I guess the issue is that #y in principle returns the number of items of y, except that a scalar like 4 has no items, but #4 is 1. Best wishes, John ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
