Oh, thanks. [If we could parenthesize constants, I guess it would be that 1p1j1000 is 1p(1j1000) rather than (1p1)j1000. And, that is documented at http://www.jsoftware.com/help/dictionary/dcons.htm - though I wonder what the advantage is.] As for the closed form representation issue, I'm not sure whether that should be significant or not. Still, it seems to be the way things are right now. Thanks again,
