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.

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 Thomas
