Ceci est une ébauche pour encourager les autres à contribuer davantage. Voici un exemple très simple pour commencer:

unit unt_asm;
{$mode objfpc}{$H+}
interface
uses
  Classes, SysUtils, LResources, Forms, Controls, Graphics, Dialogs, StdCtrls;
type
  { TForm1 }
  TForm1 = class(TForm)
    btnGo: TButton;
    edtInput: TEdit;
    edtOutput: TEdit;
    Label1: TLabel;
    Label2: TLabel;
    procedure btnGoClick(Sender: TObject);
  private
    { private declarations }
  public
    { public declarations }
  end; 
var
  Form1: TForm1; 
implementation
{ TForm1 }

procedure TForm1.btnGoClick(Sender: TObject);
var
  num, answer : integer;
begin
  num := StrToInt(edtInput.Text);
  //This is required with Lazarus on x86:
  {$ASMMODE intel}
  asm
    MOV EAX, num
    ADD EAX, 110B //add binary 110
    SUB EAX, 2    //subtract decimal 2
    MOV answer, EAX
  end;
  edtOutput.Text := IntToStr(answer);
end;

initialization
  {$I unt_asm.lrs}
end.
