What works for me with standard ascii files is:

fflush(stdout);
in_file = input("Enter name of input file: ","s");
a = load(in_file);

where a is a large matrix containing all the data that can then be copied to
other vectors/matrices as needed. The size() function can tell you how the
data are arranged.

I've never tried this with comma delimiters, just spaces.

On the same general subject, I've been removing any ascii character headers
from my ascii numeric files before loading them. Is there a way of skipping
some lines at the start of a load? I seem to remember that someone (jwe?)
said that the skip option is there but not currently functional.

A bit of elaboration in this area in the next edition of the Octave manual
would be useful.
