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) thanks is advance, ARPA: munnari!isaac@seismo Isaac Balbin UUCP: seismo!munnari!isaac Dept. of Comp Sci CSNET: isaac@munnari.oz University of Melbourne 3052 Australia P.S. Does anyone konw whether anyone has written an interface between (grn & gremlin) and a Vectrix 40 graphics terminal?

Re: the D`t construct I can't find any mention of it in my manual! As fasr as I can see, the thickened circle is achieved by increasing the point size, and this seems sensible if the typesetter can only handle lines by full-stop simulation, or if the typesetter post-processor handles it, which is what should happen!
