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

theorem Th44:
  for J being Program of SCM+FSA, i 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 J be Program of SCM+FSA;
  let i 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 i does not destroy a by A1,Th39;
  hence thesis by A2,Th43;
end;
