        !            21: 9 bits of \fInumask\fP are used whenever a file is created,
        !            22: clearing corresponding bits in the file mode
        !            23: (see

        !            25: This clearing allows each user to restrict the default access
        !            26: to his files.
        !            27: .PP
        !            28: The value is initially 022 (write access for owner only).
        !            29: The mask is inherited by child processes.
