Very helpful. I rely on the old testament book of Ossanna and on groff(7), neither of which cover that option for \D. One must look in "info groff". I hope Branden's extensive edits to groff(7) for 1.23 may correct my myopia. I could use \D'P by editing it into the output of pic, which is probably easier than what I have done before: Fill a right triangle by creating a filled box in pic and delete one corner by editing the PostScript. Then a polygon can be filled by decomposing it into right triangles and rectangles. Given groff's \D, it should be easy to add polygon support to pic. Only ignorance of git deters me from doing it myself. Doug
