Niels,
thank you very much for your help.
How can I access this bat, when I start a new session?
bat.load("person_name");
doesn't seem to work. io.print(n):
ERROR = !TypeException:user.main[1]:'n' may not be used before being initialized
Thanks
Kambiz

(ps later you probably want to switch to subcommit, ie only commit those
bat that changed, for this see the documenation in the transaction module
(src/modules/mal/transaction.mx)
