1 PROTECT
File protection is specified, for each file, to determine which type of
access each of four increasingly inclusive classes of users have to the
file. The classes of users are System, Owner (your own UIC), Group
(users with the same group code in their UIC), and World (all other
users). The types of access are Read, Write, Execute, and Delete. You
may use the EDIT/ACL command to create an Access Control List for any
file. The ACL controls the access of individual users and classes of
users to a file. 

The SET PROTECTION command lets you change the protection of any file.
You should issue a SET PROTECTION/DEFAULT command in your LOGIN.COM
procedure file to change the protection for newly created files, if the
default of (SYSTEM:RWED,OWNER:RWED,GROUP:RE,WORLD:) is not satisfactory.
This command will remain in effect for all subsequent files you create
in the current session or batch job. 

To apply a protection different than the default to an entire
subdirectory, apply that protection to the subdirectory.DIR index file
with the SET PROTECTION command. 

For details of how to specify file or volume protections, see HELP SET
PROTECTION and HELP SPECIFY PROTECTION.
