IOError:[Errno 27] File too large

[ch.valderanis at gmail.com]

Dear Steven,

Thank you very much both for your answer and of course your comments. They are taken into account.
I found out that when I touch FILENAME.sub in the command line, I get the same error. So I guess it isn't a problem with the language but rather deeper. I will solve this first before I come back.
Just for completeness:

The code is corrected according to your advice:
Here it the error:

Traceback (most recent call last):
  File "createsubmitfiles.py", line 12, in <module>
    newfile=open(newname,'w')
IOError: [Errno 27] File too large: 'FILENAME.sub;'
 
I have changed the actual filename reported by the traceback.
FILENAME.xml does exist before the code is run
FILENAME.sub is not created
FILENAME has a length of 160 characters
I do have space to write all the files in the directory

Yes. It is a constant string

When I do an ls -l before I run the code and after the code has failed, all I see are files with size <1kB.
