简单的,你现在就可以试一试:)。

-----以前学汇编的时候做的测试。第一个程序只是给您个印象,后面还有一个帖子,在详细说说。

unit Unit1;

interface

uses

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

Dialogs, StdCtrls, ExtCtrls;

type

TForm1 = class(TForm)

Shape1: TShape;

Label1: TLabel;

Label2: TLabel;

Label3: TLabel;

Button1: TButton;

Button2: TButton;

Label4: TLabel;

Label5: TLabel;

Label6: TLabel;

Button3: TButton;

procedure Button1Click(Sender: TObject);

procedure Button2Click(Sender: TObject);

//procedure Button3Click(Sender: TObject);

//procedure BtCalcuClick(sender: TObject);

private

{ Private declarations }

public

{ Public declarations }

end;

var

Form1: TForm1;

function Sum1(X,Y:integer):integer;

function Sum2(X,Y:integer):integer;stdcall;

function Sum3(var X,Y:integer):integer;stdcall;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);

var

i,j:integer;

begin

label1.Caption:=inttostr(sum1(2,3));

label2.Caption:=inttostr(sum2(2,3));

i:=2;

j:=3;

label3.Caption:=inttostr(sum1(i,j));

end;

//delphi程序求和

function Sum1(X,Y:integer):integer;

begin

result:=X+Y;

end;

//汇编求和1---

function Sum2(X,Y:integer):integer;stdcall;

begin

asm

mov eax,X

add eax,Y

mov @result,eax

end;

end;

//汇编求和2---

function Sum3(var X,Y:integer):integer;stdcall;

begin

asm

mov eax,X

mov eax,[eax]

mov edx,Y

add eax,[edx]

mov @result,eax

end;

end;

procedure TForm1.Button2Click(Sender: TObject);

begin

close;

end;

{procedure TForm1.Button3Click(Sender: TObject);

var

QuitFlag:Boolean;

OutBufPtr:Word;

begin

asm

mov al,QuitFlag

mov bx,OutBufPtr

end;

end;}

end.
