This equation for computing pS assumes that the value in number register .v is
10 times the current vertical separation set by .vs (default 12pts.).  It turned
out that in my case (DWB 2.0 printing to Imagen 8/300), the relationship
between .v and .vs was different.  The equation .vs = (.v - 2)/4 gives me
approximately the right results for typical font sizes (e.g. 10 - 18 pts.).
(Thanks to Bob Marks for help with figuring this out.)

Since I'm not concerned with double-spaced text, I use the equation
	.nr pS (\\n(nL*(\\n(.v-2)/4)
which seems to work for me.

Does anyone know of a way to find the value of the vertical separation set by .vs
without using .v, or the right equation to adjust the value in .v to get this
information independent of the destination?
