Right. My point is that when a tacit definition is not found, 13 : n is equivalent to 4 : n when 'x' is in the body. The documentation states that 13 : n will produce a "tacit verb if possible, otherwise equivalent to 3 : n" (no mention of 4 : n). Here's an example of the sort of case I'm discussing (borrowed from Henry Rich), 13 : '+:^:x y' 4 : '+:^:x y' M ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
