Thank you gentlemen -- Jurgen's way is correct. That will make life MUCH
easier now! :)
Perhaps for the next example of the pstricks user manual might have more
examples on using PostScript code? I'm happy to contribute especially
with things like
\def\Func{x COS}
\psdot(!4 PI mul 7 div /x 4 PI mul 7 div def \Func)
where the dot is created at (4pi/7, cos(4pi/7)). This I learnt from
looking at one of Herbert Voss' examples on tug.org/pstricks and would
be helpful to teachers/academics who are drawing curves.
