reserve m for Nat;
reserve P for Instruction-Sequence of SCM+FSA;

theorem
 for I being MacroInstruction of SCM+FSA, k being Nat
  holds Goto k ";" I = Macro(goto k) ';' I
proof let I be MacroInstruction of SCM+FSA, k being Nat;
  rng Goto k = {goto k} by AFINSQ_1:33;
  then not halt SCM+FSA in rng Goto k by TARSKI:def 1;
  then Directed Goto k = Goto k by FUNCT_4:103;
 hence Goto k ";" I = Macro(goto k) ';' I;
end;
