I guess this is what you mean:
     DOS			Windows
--------------	---------------
Alt+130 => '�'	Alt+0130 => '�'
Alt+233 => '_'	Alt+0233 => '�'

FUNCTION ISO ( p_car : character ) RETURN character IS

	RETURN ISO_Char;

I don't want to forbid accents in filenames.  Why should I ?
Windows (in all it's glory) accepts accents in filenames, so
why not take advantage of it with my program ?  If I'm a user
of the program and I arleady have input filenames that have
accented characters on my HD I don't want to have to change
my files' names before using the program.

If the user is using my program in a DOS window, what he/she
enters (each character) will be the code from the Windows
code page, and if it's in DOS MODE (reboot) it will be from
the DOS 850 code page, right ?

If the above is true, then the function ISO will only have
an effect if the user is in DOS MODE, right ?

So if the two statements above are true, then how come
I have a problem (explained in my first post), since I've
been working in a DOS window all along when playing the
user part and when coding ?

For 0-127 (Ascii) the code is the same:
	Alt+63 (DOS) => '?' and Alt+063 (Windows) => '?'.

Is there a chance that something related to this topic
is causing the problem when there's a '?' in the filename ?
Of course it could be my code that is faulty, but I doubt
it since the other validations, in the same procedure,
are working fine (see my first post).

Thanks

Marc
