how to run python file from the python IDLE editor

[Seid Mohammed]

hi all,
I have a problem.
when i run a file "python xxx.py zzzz" from a comand line, it just work.
But the DOS command line do not support unicode and I want to run it
just from the IDLE editor.
i can run by pressing F5, but without an argument
anybody can hint me how to run with an argument just in the Python IDLE editor

Thanks a lot
Seid M.
