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.
