How?  In the standard interpreter, 'exit' is bound to the string
'Use Ctrl-Z plus Return to exit.'
so trying to call it as a function fails.

The interactive interpreter runs a statement at a time and gives a prompt 
after any output.  From a command shell, you can use a flag (-i I think) to 
enter interactive mode after the script end.
