Richard,

Fixed -- sent to lily list. Also, I mistyped -- one must know "points" and not pixels to use embedded postscript like this. I did some exploration last night on how that works trying to setup boxes that work on left/right margins at .75" (.75 * 72 points = 54 points), and top/bottom margins at 1.25" (1.25 * 72 points = 90 points) and though I did get a box, its right/top edges are not correct. So, still working on it. I do now understand your postscript code and what it does. I found a very nice introduction (http://paulbourke.net/dataformats/postscript/) that gave me the information I needed.

Q: how did you determine the point values you used?

Regards,

Guy

I thank you because you answered by question.
It seems this didn't get posted to the mailing list, which would be a
shame as this reply seems to be the one that solved your problem.

 This might be 
worth an LSR, because it can be used to "draw" a box around anything
as 
long as one knows page dimensions by pixels.
It could be that there is nothing like this in the LSR - I *think* the
gsave ... grestore thing was something I devised when customizing
Nicholas Sceaux's title page work, so it could be a trick that is not
widely known...
