positional
                      parameters are unset.  Otherwise, the positional
parame‐
                      ters  are  set  to  the args, even if some of them

 to
                      be assigned to the positional parameters.  The -x and
-v
                      options are turned off.  If there are no args, the
posi‐
                      tional parameters remain unchanged.
