I had this flow chart type of graph. I wanted to alter it by
changing all the dashed boxes to ellipses (with a thickened edge).
So, I used the following definition of a thickened ellipse ...

define teli	_	"\D't 8u'"
ellipse $1
"\D't 3u'"	_

where,
$1 was some text inside the ellipse,
\D is a PIC lowlevel thing.
Now, I borrowed the \D't 8u' construct from the PIC user manual by BWK
revised edition March 1982. This gives an example to make thickened
concentric circles on or about page 15 in my copy.
However, the result was unexpected. Whilst the ellipse came out thicker,
the positioning was all wrong.
I mailed BWK about it, but he seems never to have heard of the
\D't 8n' construct! He says he knows of \D'e and \D'c but none alter the 
thickness. I suppose that I could change the point size, but .....
has anyone done this before ... Do your manuals also have \D't ?
Is this a bug with ditroff maybe? (maybe a typo in my manual)

P.S. Does anyone konw whether anyone has written an interface between 
(grn & gremlin) and a Vectrix 40 graphics terminal?
