theorem
  for I being good parahalting really-closed MacroInstruction of SCM+FSA,
      a being read-write Int-Location st I does not destroy a
   holds Initialize((intloc 0).-->1)  is Times(a,I)-halted
proof
  let I be good parahalting really-closed MacroInstruction of SCM+FSA;
  let a be read-write Int-Location;
  assume
A1: I does not destroy a;
  now
   let s be State of SCM+FSA;
   let P be Instruction-Sequence of SCM+FSA;
    (Initialized s).intloc 0 = 1 by SCMFSA_M:5;
   hence Times(a,I) is_halting_on Initialized s,P by A1,Th56;
  end;
  hence thesis by SCMFSA8C:5;
end;
