You're right, I did not explain very good my needs.
I was debugging a tk app, and since I'm a newbie, I was restarting it
again and again, after every little correction (wich sometimes weren't
still correct...). I tougth then that it would be a fine thing if I
could just tell the tk interpreter "re-read the script and apply all
changes I made". But as you tell me, such a command does not exists...

thanks anyway
