I hope not.  What would you expect to happen when attempting to write a 
file?  Perhaps you want to open with "u"?  Or maybe you should check to see
if it's already in existence.  But the behavior you quote is the proper and
expected.

Thats interesting... it will have capital letters when created with a DOS (EX),
but lowercase with Windows (EXW).

You can use open("debug.txt", "r") to see whether or not the file exists. It
will return -1 if it doesn't exist.

About the ALL CAPS filename, i believe that is because it is using the DOS file
formate. The reference manual says:

"DOS32:  When running under Windows 95 or later, you can open any existing file
that has a long file or directory name in its path (i.e. greater than the
standard DOS 8.3 format) using any open mode - read, write etc. However, if you
try to create a new file (open with "w" or "a" and the file does not already
exist) then the name will be truncated if necessary to an 8.3 style name. We hope
to support creation of new long-filename files in a future release."

To create a file with a long filename, maybe you could try somehting like this:

fn = open("debug.txt", "w")
close(fn)
system("rename DEBUG.TXT debug.txt", 2)
fn = open("debug.txt", "w")

Just an idea. I can't test this right now, because I switched to linux!

I'll apologize early for my sarcastic reply (just my nature)...  I could have
just as easily stated that DOS is based on 8-bit systems that had no room for
lower-case characters.

No hard feelings intended :)
