let k1, k2 be Integer; :: thesis: for a, b being Int_position holds not MultBy a,k1,b,k2 is halting
let a, b be Int_position ; :: thesis: not MultBy a,k1,b,k2 is halting
consider s being State of SCMPDS ;
(Exec (MultBy a,k1,b,k2),s) . (IC SCMPDS ) = Next (IC s) by Th63;
hence not MultBy a,k1,b,k2 is halting by Th76; :: thesis: verum
