One obvious difference is that 2: is a function, in the mathematical sense, while 6!:0 is not a function. In fact, 2: corresponds to the polynomial 2&p. except that its domain has been extended to cover literals and boxes. Meanwhile, 6!:0 is not a function -- let alone a polynomial -- over any domain, as 6!:0 depends on the computing environment. (This is probably going over ground you have already thought about, but I think it's worth mentioning.) -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
