File Mode Number 0

File mode number 0 has no special meaning for SFS. In a minidisk environment, file mode number 0 makes the files private. Because all SFS files are private unless you explicitly grant authority to someone, file mode number 0 is not meaningful for SFS files. If you do use file mode number 0, SFS treats the file as though it had a file mode number of 1. Users who can read from your SFS directories can see the names of the files within that directory, regardless of the file mode number.
