Thanks for the "wt" advice, Avraha. I worked perfectly. I guess I 
didn't read "help fopen" closely enough.

As far as I know the forward slash means the same thing in both the 
Linux and Mac systems. "Output/portfolioValues.csv" just points to a 
specific file in the "Output" directory.

At the beginning of my script, "portfolioValues.m", I execute another 
script, "spdrData.m", which contains the path to an "Octave" 
directory in the variable "octaveDir". Then I do
    chdir(octaveDir);
Now "Output/portfolioValues.csv" points to 
"/.../Octave/Output/portfolioValues.csv".
In fact my octave script is actually "/.../Octave/m/portfolioValues.m".

I hope this explains it.

Regards,

Vic
