SET-FILE-ACCESS

A file may be protected from unauthorized use by the command:

@SET-FILE-ACCESS <file name>, <public access>, <friend access>, <owner access>

Set public, friend and owner access of a specified file. Separated access modes may be specified for the owner of a file, for other users declared as friends and for all other users of the installation. If an access string is empty, ie. only the comma separator or a carriage return is given, the access mode for that user group is not changed.

<file name>

(default type = SYMB) file name.

<public access>

access modes for public.

<friend access>

access modes for friend.

<owner access>

access modes for owner.

Rules:

1. Permitted for all users with directory access to the file.
2. The access type can be any relevant combination of the characters (except N which must stand alone):

R - read permitted
W - write permitted
A - append permitted (write from maximum byte pointer)
C - common access permitted (access by more than one user)
D - directory access permitted (the file may be created, deleted, legal access mode changed and new version created)
N - no acccess permitted

1. @FILE-STATISTICS can be used to check the access types for the file.

Example:

@SET-FILE-ACCESS F-1:DATA N, N, RWACD

Public and friend has no access to the file F-1:DATA. Owner has full access.
