I like to think of J as providing primarily primitive recursive features, where other languages focus on recursive features. This is not completely accurate, but for the most part it works. J's array processing is, in essence, considerably simpler than some analogous possibilities. And, simplicity is a virtue. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
