RE: startup with .octaverc on Windows Vista

[Richardson, Anthony]

We have a similar setup.   We set HOME in the
C:/octave/3.22.2_gcc-4.3.0/share/octave/site/m/startup/octaverc
file, with the following lines:

setenv('HOME','h:\');
cd ~;

This allows the octave HOME env variable to be set differently 
than a Vista global HOME environment variable.  An .octaverc 
file in h:\ is still executed.  Setting HOME from Windows
should work too, but we have other software that uses the HOME
environment variable and requires that it be set to something
else.
