Delphi结构体数组指针的问题

//这段代码在Delphi 2007和delphi 7下是可以执行的，所以正确使用结构体数组和指针应该是这样的，已验证


unit Unit1;

interface

uses

  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

  Dialogs, StdCtrls;

type

  TForm1 = class(TForm)

    Button1: TButton;

    Memo1: TMemo;

    procedure Button1Click(Sender: TObject);

  private

    { Private declarations }

  public

    { Public declarations }

  end;

var

  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);

type

   TMyType = record

     S: String;

     I: Integer;

    end;

   TMyArray = array of TMyType;

   PMyArray = ^TMyArray;

 var

   MyArray: PMyArray;

   i:integer;

    AList:TStrings;

begin

  try

    new(MyArray);

    AList:=TStringList.Create;

    SetLength(MyArray^, );

    for i:= to  do

    begin

      MyArray^[i].S :='中山'+inttostr(i);

      myArray^[i].I :=i;

      AList.Add(MyArray^[i].S+',年龄为：'+inttostr(MyArray^[i].I));

    end;

   self.Memo1.Lines:=Alist;

  finally

     SetLength(MyArray^, );

     Dispose(MyArray);

  end;

end;

end.
