reserve m,n for Nat,
  I for Program of SCM+FSA,
  s,s1,s2 for State of SCM+FSA,
  a for Int-Location,
  f for FinSeq-Location,
  p,p1,p2 for Instruction-Sequence of SCM+FSA;

theorem Th42:
  for s being State of SCM+FSA, I being InitHalting Program of
  SCM+FSA, a being read-write Int-Location holds IExec(I,p,s).a
   = Comput(p +* I, Initialize Initialized s,
  LifeSpan(p +* I,Initialize Initialized s)).a
proof
  let s be State of SCM+FSA,I be InitHalting Program of SCM+FSA;
  let a be read-write Int-Location;
  I is_halting_on Initialized s,p by Th41;
  hence thesis by SCMFSA8C:58;
end;
