              less than or equal to $#.  If n is 0, no parameters  are  changed.   If  n  is  not
              given,  it  is assumed to be 1.  If n is greater than $#, the positional parameters
              are not changed.  The return status is greater than zero if n is greater than $# or
              less than zero; otherwise 0.
