The documentation says that "dn" is only valid AFTER a diversion; I'm
not sure if that's what you mean. (It may be valid during, but I'm not
sure if you can count on it.) But one thing I *am* sure about is its
units are the "basic units", not the number of lines. That is, in troff,
your lines are 400 units high, and in nroff they are 320. I haven't tried,
but you can probably get number of lines by dividing dn by .v.
