Volume and file protection is specified as follows:
(SYSTEM:RWED,OWNER:RWED,GROUP:RWED,WORLD:RWED)
There are four categories of protection: one for system
processes, one for the owner of the file, one for other members
of the owner's group, and one for members of other groups. For
each category, any combination of four different types of access
may be specified:
R read access
W write access
E execute access (for execution of images)
D delete access
If you want to deny all access to a category, you must specify
the category name without a colon, for example:
/PROTECTION=(OWNER:RWE,GROUP,WORLD)
For complete information on setting protections, see the HP OpenVMS
Guide to System Security.
