我在自定义的PROCEDURE中怎么不能调用EDIT? (50分)

急,在线等!
unit Unit2;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs;

type
TForm2 = class(TForm)
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form2: TForm2;

implementation

{$R *.dfm}

procedure pr;
begin
eidt1:='';//怎么不可以用??怎么改
end;
end.

PROCEDURE的位置在那儿？

??不懂，你要问什么？把程序列出来

应该这么写：
procedure TForm2.pr;
begin
eidt1:='';
end;

procedure pr;
begin
Form2.eidt1.text:=''
end;

......

多人接受答案了。
