    Edit3: TEdit;
    procedure fortodoClick(Sender: TObject);
    procedure fordowntodoClick(Sender: TObject);
    procedure whiledoClick(Sender: TObject);
    procedure repeatuntilClick(Sender: TObject);
    procedure btpangkatClick(Sender: TObject);
    procedure keluarClick(Sender: TObject);
  private
    { Private declarations }

    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.fortodoClick(Sender: TObject);
var
i,j:integer;b:string;
begin
b:='';j:=2;
for i:=1 to 10 do
begin
b:=b+inttostr(j)+' ';
j:=j+2;
end;
label1.Caption:=b;
end;

procedure TForm1.fordowntodoClick(Sender: TObject);
var

end;

procedure TForm1.whiledoClick(Sender: TObject);
var

var
bil,hasil,pangkat,a:integer;
begin
bil:=strtoint(edit1.Text);
hasil:=bil;
pangkat:=strtoint(edit2.Text);
if edit2.text='0'then edit3.Text:='1'else
if edit2.text='1'then edit3.Text:=edit1.Text else
begin
for a:=2 to pangkat do

edit3.Text:=inttostr(hasil);
end;
end;

begin
close;
end;

end.
