So it does with me, but the user does not enter the filename, he launches my Python script file from the DOS-prompt with a command line parameter, for example: test.py c:\test.txt In that case the \ escapes the t. (read on!) That is, until now. For some very strange reason it suddenly works as expected. I don't understand it anymore, but never mind. Maybe I changed my little proggie somehow, causing it accidentally to work. Thanks anyway. George -- http://mail.python.org/mailman/listinfo/python-list
