Dear All, I have added two files (a source file sourcepr, and its processed PDF file sourcepr-3.pdf) in the directory https://www.agsm.edu.au/bobm/groff/
This is a slideshow for a presentation; it uses eqn, grap, and tbl, with some unusual fonts for display. Enjoy, Robert Marks -- https://www.agsm.edu.au/bobm <http://www.agsm.edu.au/bobm> 0407665644
