Re: A Gnuplot question

[Vic Norton]

Here's the situation.

The first lines of a gnuplot script are

   #!/usr/local/bin/gnuplot

   ## SE_2006-09-15_rank9.plot

   cd "~/octave/Markowitz_critical_line/Gnuplot";
   load 'data/assetSEpoints_2006-09-15_rank9.pts';
   load 'data/efficientFunctions_2006-09-15_rank9.fcn';

I want to distribute the folder, "Markowitz_critical_line", but  
clearly the gnuplot code is NOT portable unless a receiver of the  
distribution puts this "Markowitz_critical_line" folder in his own "~/ 
octave" directory.

The gnuplot script is in "Markowitz_critical_line/Gnuplot"; so what I  
really want is

   cd HERE;

where HERE is the directory of the calling script. Then the next two  
"load" lines will work fine no matter where someone puts the  
"Markowitz_critical_line" folder.

So my question is this: How do you define HERE in gnuplot?

In octave

   HERE = fileparts(mfilename("fullpath"));

Vic
