        !            12: The COHERENT system normally invokes  login as part of the log in

        !            16: the account has a password, login asks for it.
        !            17: 
        !            18: If  the user  logs  in successfully,  login then  reads the  file

        !            20: contents  on  the screen,   then  notifies the  user  if mail  is

        !            28: blank,  login  executes   sh,  which  executes  the  contents  of

        !            33:
