Re: A Gnuplot question

[Vic Norton]

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.

Regards,

Vic
