Re: Starting Octave Windows XP

[Michael J. McCann]

Tatsuro,
        Thank you for your help. I also got some pointers from 
others (a very helpful community!) and I can see what you did, so 
that is helpful. It looks as if I'm trapped by the inability of 
Octave to follow CD instructions when the folder names contain 
spaces. I don't give files or folders such names, but Windows XP Home 
does and, what's more, it doesn't list the short form in DOS command 
window DIR listings.
        Maybe you have a way to avoid it or your system is better set up.
Thank you,
Mike.
