### 16.17 PERMISSIONS

         PERMISSIONS
                 FILE='file_name'
                 /PERMISSIONS = {READONLY,WRITEABLE}.

`PERMISSIONS` changes the permissions of a file. There is one mandatory subcommand which specifies the permissions to which the file should be changed. If you set a file's permission to `READONLY`, then the file will become unwritable either by you or anyone else on the system. If you set the permission to `WRITEABLE`, then the file will become writeable by you; the permissions afforded to others will be unchanged. This command cannot be used if the `SAFER` (see SET) setting is active.
