Your basic problem is that '+' is not a PostScript operator.  What you want
to say is '1 1 add'.

I've used this program under X11r3 with mixed results.  It's a little buggy,
and I can't get path reversals to work.  I was trying to draw an annulus on
the screen with the code that works on a LaserWriter.  You need to call
reversepath so the hole in the middle isn't filled.  Unfortunately this
doesn't work in freeware PostScript.

Still, it is free and it works on the screen.  Also, most basic things like
lines, arcs, and fonts work.  Fonts are slow to draw, though.

Hope this helps,
