FWD: Re: load function with ascii text file

[Philip Nienhuis]

Hi Rod,

please keep the mailing list in cc.

Kai was the first to try :-)
Good on you that you found the issue & thanks for reporting back.

We really hope you get to like Octave. I have both Matlab and Octave at 
work but I use Octave much more.
