Do I understand correctly?
You want gnuplot to tell you the directory containing the shell-script
that called it?
bens-macbook:~ bpabbott$ pwd
/Users/bpabbott
bens-macbook:~ bpabbott$ gnuplot

I don't see what that has to do with making code portable. Can you be
more specific?

Unfortunately "help cd" is no help, Thomas.
Syntax:
cd '<directory-name>'
works if you know the directory-name. I want the Gnuplot script to
tell me the name of the directory in which it resides. Then the code
will be portable.
The Octave and Perl segments below do exactly that. The main
ingredients have nothing to do with cd or chdir. The main ingredients
of the Octave code are fileparts and mfilename. The main ingredient
of the Perl code is the FindBin package.

I realize this is not an Octave question per se, but perhaps someone
here can answer it.
My question: How do you change directory in Gnuplot so that your
working directory is the directory containing the calling script?
I know how to do this in Octave:
basedir = fileparts(mfilename("fullpath"));
chdir(basedir);
I know how to do it in Perl:
use FindBin qw($Bin);
chdir $Bin;
But I don't know how to do it in Gnuplot.
help cd
which, btw, works in Octave as well
