Hi:

It's not possible to setuid a python script, so I don't see how execfile
or exec is any more dangerous than the user creating a shell script that
rm -rf * things, and then running it.
Bash exec's scripts all the time that users create and provide.

Here's the answer to this question.
The summary of the question: how to run a module (called myapp.py) from
another module (called myappwin.py) and be able to access the namespace of
myapp.py from myappwin.py.

What do you mean, objects are saved in another object?
doc.py has a dictionary. When the user describes a wall, it is passed
to the doc object to be saved in the dictionary.
What happens if the user launches appwin with a different argument?

This is my thinking too.

Kene,
are you sure your length is 120? It seems to be 25. I did these
calculations with length = 25 and then your numbers make perfect sense.

Thanks. You are right I was actually using 25
