Embedded Python and sys.exit()

[Harald Angelow]

I have embedded Python in a  Win MFC program and execute script files and
simple strings.
(Py_RunFile, PyRun_String)

If the python script raises SystemExit or calls sys.exit() the whole process
is shut down.
How can I manage that only the Python Interpreter stops and returns from the
function call of
Py_RunFile or PyRun_String? Does Python know, that it is embedded?

thanks Harald
