it returns a vector of primes less than y+2 (i.e., if y+1 is prime, it is returned), sorted according to the sign of y (if y>0 implies /:~ and y<0 implies \:~ ) And there actually may be more hidden depths for weirder arguments. Not sure. Is anyone interested in posting a more difficult challenge? -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
