theorem
  (i1 ';' i2 ';' i3 ';' i4 ';' i5 ';' i6 ';' K).0 = i1
 proof
  LastLoc(i1 ';' i2 ';' i3 ';' i4 ';' i5 ';' i6) = 6 by Th34;
  hence (i1 ';' i2 ';' i3 ';' i4 ';' i5 ';' i6 ';' K).0
         = (i1 ';' i2 ';' i3 ';' i4 ';' i5 ';' i6).0 by Th23,Th28
        .= (i1 ';' i2 ';' i3 ';' i4 ';' i5 ';' Macro i6).0
        .= i1 by Th39;
