Hello, simple question. This behaviour surprised me.
(a,a=.?@#)'01234' 2 4 3 : 'a,a=.?@#y' '01234' 1 1 Why a is not equal to a in the first case? How can I save the roll as an intermediate result in the tacit version? Thanks. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
