You can change your password in one of two ways.  Either type a "%" before your
programmer name when you log in (e.g., type "L %PRG" instead of "L PRG" if your
programmer name is "PRG"), or give the UFD command if you are already logged in.
In either case you will be asked for your current password and then be given an
opportunity to choose a new password and change your default file protection and
your directory protection.  (Type <return> to these questions if you do not want
to change protections.)
