Essentially MS-Windows is treating the .py file as a document and using python to "open" the document. Try running you program as: python process.py <test.txt Note for this to work python will have to be on your path. If it isn't use the full path to you copy of python. for e.g.: c:\python25\python.exe process.py <test.txt Rob. -- http://www.victim-prime.dsl.pipex.com/ -- http://mail.python.org/mailman/listinfo/python-list
