I don't think anybody will argue that J is a computer algebra system but: 1 + x: 1x1^1p1 * 0j1 0 Or: e_exp=: x:@^ 1 + e_exp 1p1 * 0j1 0 I suggest that you first enjoy J for what it can do before you try to make it something it isn't. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
