Open the database file \var{filename} and return a corresponding

opened in the other DBM implementations, is ignored in
\module{dumbdbm}; the database is always opened for update, and will
be created if it does not exist.
The optional \var{mode} argument is the \UNIX{} mode of the file, used
only when the database has to be created. It defaults to octal
\code{0666} (and will be modified by the prevailing umask).
