Bill responded: > I'd wonder if that were a call for &. . The short answer is you can't use &. in this case. The result of the phrase of f&.g is the output of g^:_1 . But in your case the result is the output of lsfit , not |:^:_1 (aka |: ). Put another way, your verb's pattern is f g^:_1 (something) g data . Whereas &. expands to g^:_1 f g data . -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
