let k1, k2 be Integer; :: thesis: for a being Int_position holds not AddTo (a,k1,k2) is halting
let a be Int_position ; :: thesis: not AddTo (a,k1,k2) is halting
consider s being State of SCMPDS;
(Exec ((AddTo (a,k1,k2)),s)) . (IC SCMPDS) = succ (IC s) by Th60;
hence not AddTo (a,k1,k2) is halting by Th76; :: thesis: verum
