怎么样调用其它窗体的过程？(100分)

比如,我在unit1定义好了，想在unit2调用
随便再一下，我这样定义 procedure loadtv，算不算是定义一个过程？
小弟不才，基础不是很好
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms；
type
TForm_main = class(TForm)
procedure loadtv; //加载treeview
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form_main: TForm_main;
implementation
{$R *.dfm}
procedure TForm_main.loadtv;
begin
......
end;

unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms；
type
TForm_main = class(TForm)
procedure loadtv; //加载treeview
private
{ Private declarations }
public
{ Public declarations }
procedure loadtv;
end;
var
Form_main: TForm_main;
implementation
{$R *.dfm}
procedure TForm_main.loadtv;
begin
......
end;
/////////////////////////////////////
unit Unit2;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms；
type
TForm2= class(TForm)
procedure loadtv; //加载treeview
private
{ Private declarations }
public
{ Public declarations }
procedure loadtv;
end;
var
Form2: TForm2;
implementation
uses unit1;
{$R *.dfm}
procedure TForm2.loadtv;
begin
Form_main.loadtv;
end;

把这个loadtv过程写到public里
在unit2的implementation段里uses这个unit1，然后就可以调用了，unit1.loadtv

多人接受答案了。
