Yeah, I figured out that 'single' variable stuff later.
Using x = randn(1000,2000) I looked at the format of the
text file after saving
octave-2.9.12.exe > save -ascii "mybigfile4.txt" x;
and found all those size headers were missing. just data
with no information.
by the way, 2.9.12 is a screamer making random numbers
compared to 2.1.50
So not being able to read the information header section
# name: x
etc is a bug?
