reserve m for Nat;
reserve P,PP,P1,P2 for Instruction-Sequence of SCM+FSA;

theorem Th45:
  for I being Program of SCM+FSA, j being Instruction of SCM+FSA, a
being Int-Location st I does not destroy a & j does not destroy a holds I ";" j
  does not destroy a
proof
  let I be Program of SCM+FSA;
  let j be Instruction of SCM+FSA;
  let a be Int-Location;
  assume that
A1: I does not destroy a and
A2: j does not destroy a;
  Macro j does not destroy a by A2,Th39;
  hence thesis by A1,Th43;
end;
