Miscellaneous Features

• Read-only mode:

        use Fcntl 'O_RDONLY';
        tie @FILE, 'Tie::File', $myfile, mode => O_RDONLY;

• Change the record separator string:

        tie @FILE, 'Tie::File', $myfile, recsep => ";;";

• Tie an open filehandle:

        tie @FILE, 'Tie::File', \*STDIN, mode => O_RDONLY;

• Lock the file:

        use Fcntl ':flock';
        (tied @FILE)->flock(LOCK_EX);

• (Locking is another advantage over DB_File)
