For counting numbers, would it be useful to have special code for >:i. ?
I think this would meet the RR (Roger Requirement) of being more than twice as fast. I have to comment that in APL I sometime got in trouble sharing code with varying IO - e.g. if a function set a local []IO then it better not use a function that assumed a different value. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
