Yes; you may want to take a look at

        plugins/gnuplot/progs/init-gnuplot.scm

The routine 'gnuplot-serialize' defines a custom routine
for string serialization. The idea is that the input *tree*
is converted to a string before passing it to asir.
This conversion involves rewriting fractions to
the ()/() notation, superscripts to ^(), etc.
What you may want to do is take the output of
the usual routine and replace the "\n" by something else.

Best wishes, Joris
