options: Have the child set it's exit code to indicate success or failure and use one of the various os.wait functions in the parent to retrieve it. or create a pipe before forking and you can pass data back and forth between the parent and child or look at one of the shared memory libraries -- Jim Segrave ([EMAIL PROTECTED]) -- http://mail.python.org/mailman/listinfo/python-list
