very weird problem loading datafile (sounds like a bug)

[francholi]

Hi, I have a set of ascii files, named from 0 to 9, I'm loading these files to calculate covariance matrices and eigenvectors,
everything works fine, but I'm having trouble to load file named 7.....so, you are thinking, "and what?",
well, it's just that, the file named 7 doesn't load, if I rename it to "70", it loads fine, if I rename the file named 0 to 7, then the file that 1 minute before worked perfect, now named as 7 just doesn't load.
Somebody please can tell me, why in the hell, just the file named 7 doesn't load ????
I tried from octave console, from bash as an argument, any name works fine, but "7" doesn't work.
I really feel like a stupid, so anyone can start his response in any terms, I'll no take it as an offense.

I'm using
Ubuntu Linux,
Octave 3.0.0,
Octave was configured for "i486-pc-linux-gnu".
kernel 2.6.24,

I can't put here the contents of my very super secret files, so a very simple test of my problem is:

octave:1> a = [1 2];
octave:2> save("7","a");
octave:3> load("7")

Invalid call to load.  Correct usage is:

 -- Command: load options file v1 v2 ...


Additional help for built-in functions and operators is
available in the on-line version of the manual.  Use the command
`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW
at http://www.octave.org and via the [e-mail]
mailing list.

octave:3> save("8","a");
octave:4> load("8")
octave:5>

Please, try this at home and tell me that I'm not crazy......

thanks for listening and sorry for my english.
Francisco.

pd. I did a quick search in the list and I didn't find anything similar to my problem, please sorry if it's a known problem....

No, you definitely are not crazy. It's a minor bug and the cause is
not hard to guess:
the -7 option is parsed incorrectly. Attached a fix.
