Default file protection mode per subdirectory

[Marshall D. Abrams]

I would like to establish a default file protection mode on a subdirectory
basis, rather than for all my files.  I am presently using umask in my .login,
but that causes the same default for all files.

Is there some other feature/command that I could use?  I am running on a
Sun 3.0.  Please reply directly, as I am not on info-unix.

Thanks.

Sincerely,
