NAME              chmod -- change mode of file

SYNOPSIS          sys         chmod; name; mode          / chmod = 15.

DESCRIPTION       The file whose name is given as the null--terminated string
                  pointed to by name has its mode changed to mode. Modes are
                  constructed by oring together some combination of the
                  following:

                        01   write, non--owner
                        02   read, non--owner
                        04   write, owner
                        10   read, owner
                        20   executable
                        40   set user ID on execution

                  Only the owner of a file (or the super--user) may change
                  the mode.
