Regarding your "72000", this will refer to 72000 "millipoints".
In current standard orthograhy, 1 point is 1/72 of an inch,
amd what I call a "millipoint" is of course 1/1000 of a point.
It is ths standard unit (groff "u") for PostScript output
("devps" output device). So "72000" in \n[.o] denotes a page-offset
of 1 inch in devps.Other output devices may use different dimensions for "u". These can be found as "res" (resolution) in the "DESC" file for the output device'. Thus: .../font/devps/DESC : "res 72000" .../font/devascii/DESC : "res 240" .../font/devdvi/DESC : "res 57816" and so on (the last, devdvi -- as used by TeX -- can in the politest terms be described as "inconvenient"). Hoping this helps, Ted.
