  TForm1 = class(TForm)
    Button1: TButton;

    { Private declarations }
    Function call:integer;
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementation{$R *.dfm}{ TForm1 }procedure TForm1.aaa;
begin
  showmessage( 'hello world' );
end;procedure TForm1.Button1Click(Sender: TObject);
begin
  call;
end;function TForm1.call: integer;
var
  PAddr: Pointer;
begin
  try
    PAddr := TForm1.MethodAddress('aaa');
    if PAddr <> nil then
    asm
      mov eax, TForm1
      call PAddr
      mov Result, eax
    end;
  except
  end;
end;end.

Answer 3

procedure ProcName;
begin
  Application.MessageBox('ddddddddd', 'dddd', MB_OK);
end;procedure TForm1.btn1Click(Sender: TObject);
var
  Proc: TProcedure;
begin
  Proc := @ProcName;
  Proc;
end;

Answer 4

上面的理解错意思了，简单更正一下：procedure TForm1.btn1Click(Sender: TObject);
var
  Proc: TProcedure;
begin
  Proc := TForm1.MethodAddress('ProcName');
  if Assigned(Proc) then Proc;
end;
