Thank you, Vadim
But, how can I transfer parameters to gnuplot? The objective is to do things
equivalent to
system("wgnuplot -persist maxout.gnuplot") /*windows*/
or
system("(gnuplot -persist maxout.gnuplot; rm -f maxout.gnuplot)&") /*linux*/
[If I don't remove the file in Linux, I can't call gnuplot a second time. This
is not necessary in MS-Windows]
If I write:
(%i13) system("gnuplot -persist maxout.gnuplot");
I can see the plot, but the following does not work:
(%i14) concat(gnuplot_command," -persist maxout.gnuplot");
(%o14) gnuplot -persist maxout.gnuplot
(%i15) system(%);
/bin/sh: line 1: gnuplot -persist maxout.gnuplot: command not found
On the other hand, I know there is a variable at lisp level, *autoconf-win32*,
that equals true in the MS-Windows environment, and false otherwise. Is it
possible to transfer this value to a variable at Maxima level?
