Hello, I'm getting 'length error, executing monad (i.x)&|' for ((i.3) & |."(0 _) ]) i.3
but not for (i.3) ([ |."(0 _) ]) i.3 Why is that? Other primitive dyads work in rotate's place. Current nuvoc page on rotate has nothing relevant. I well may be be missing something obvious. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
