Just to be clear, this behavior is unrelated to 6!:0 specifically. It is exhibited by all f"0 y where 0 e. $ y (whether the "0 is, to borrow a phrase, express or implied). Basically you're asking to operate on all the scalars of an array which contains no scalars. Now, there are some cavaeats; notably regarding verbs with side effects. Further, the display, while empty, can can be arbitrarily tall and wide, depending on the rank of (f"0) 0 . -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
