[texhax] using postscript functions

[Fred Moore]

Dear Herbert:

I should like to be able to calculate a point in a pspicture.
For example a random point, such as should be shown in
the second picture --- if it would compile.
=================================================
\noindent
\psset{unit=10pt,arrowsize=2.5pt 3}
\pspicture(0,0)(+23.5,+12.0)
\psframe[linewidth=0.4pt,linecolor=green](0,0)(+23.5,+12.0)
\parametricplot[plotpoints=500,linewidth=0.2pt,plotstyle=dots,
linecolor=blue]{0}{2}%
{rand 2350 mod 100 div rand 1200 mod 100 div}
\endpspicture

\vskip10pt
\noindent
\psset{unit=10pt,arrowsize=2.5pt 3}
\pspicture(0,0)(+23.5,+12.0)
\psframe[linewidth=0.4pt,linecolor=green](0,0)(+23.5,+12.0)
\rput({rand 2350 mod 100 div},{rand 1200 mod 100 div}){X}
\endpspicture
==================================================
Any suggestions or advice, please.

regards,
Fred
