[net.wanted] GRAP - A Language for Typesetting Graphs

mie@teddy.UUCP (Martin I. Eiger) (04/29/85)

I have a copy of a document called "GRAP - A Language for Typesetting
Graphs, Tutorial and User Manual", by Jon Bentley and Brian Kernighan of
Bell Labs.  It is a preprocessor which works with PIC and TROFF and can
produce all sorts of different graphs on a typesetter.

I covet this facility.  I have TROFF and a typesetter, but I don't have GRAP
or PIC.  Can anybody provide any pointers?

Many thanks.

PIC is supplied with Documenter's WorkBench and also in the TITROFF
package from Bell Labs (is this still available?).  I have adapted
PIC to work with either the older (C/A/T) troff for DITROFF.
For GRAP, you need the newer, more programmable, version of PIC
described in BWK's latest revision of the PIC manual.  I don't know
how one gets hold of the newer PIC; I'm thinking about hacking on
the older version to bring it up to date (but hate having to do so).

I haven't heard how to get GRAP either.  Given the new PIC, it looks
simple enough to reinvent if necessary..
