  In FastReport, you can use TfrxMemoView.
  
  QR: QRLabel1.Caption := 'some text'; //*Delphi code
  FR: frxMemoView1.Memo.Text := 'here, too.'; //*FastScript code
  
  And...
  If you want to assign some event handlers in FastReport, you do by same way of Delphi.
  
  sample code:

  //In Delphi
  procedure TMainForm.PrintReport(const APreview: Boolean);
  begin
    //set FastReport variable
    frxReport1.Variables['TextVar1'] := '''' + ToimitusehtoEdit.Text + ''''; //*IMPORTANT* if you use string variables, quote by '.
    frxReport1.Variables['TextVar2'] := '''' + FloatToStrF(CalculatedValue,ffNumber,15,0) + '  ??¬' + '''';
    frxReport1.Variables['TextVar3'] := '''' + Saler2B.text + '  mm' + '''';
    frxReport1.Variables['TextVar4'] := '''' + Optioner.Rs_Name + '''';
    frxReport1.Variables['TextVar5'] := '''' + Optioner.Rs_Address + '''';
  
    //execute print or preview
    if APreview then
    begin
      frxReport1.ShowReport;
    end
    else
    begin
      frxReport1.PrepareReport;
      frxReport1.Print;
    end;
  end;
  
  
  //In FastReport
  procedure Page1OnBeforePrint(Sender: TfrxComponent);
  begin
    frxMemoViewTarjous1Toimitusehto.Memo.Text := <TextVar1>;    //An Edit:Variables of the type "String" from the Main Form
    frxMemoViewTarjous1hintaan.Memo.Text      := <TextVar2>;    //Variable of the type "Double" converted to String
    frxMemoViewTarjous1Lasinleveys.Memo.Text  := <TextVar3>;    //An Edit
  
    frxMemoViewRs_Name.Memo.Text              := <TextVar4>;    //Variables of the type "String" from Unit "Optioner"
    frxMemoViewRs_Address.Memo.Text           := <TextVar5>;
  end;

  Hi,
  
  I am unable to comply the code following your suggestion and enlightenment herein.
  
  The name of the memo in frxReport1 is
  Memo3: TFrxMemoView
  
  ERROR
  E2003 Undeclared identifier: frxMemoViewMemo3
  
  What is wrong in my code (see below)? I using FastReport 4.13.2 for Delphi XE5.
  
  Regards,
  Alex

  since you are working from delphi code you must use the findobject method to find the object before you try to access its properties.
  see the programmers manual on working with report objects

  Hi again,
  
  My suggestion means that you should set the porperty of TfrxMemoView component *in FastScript*.
  
  In your case, the name of TfrxMemoView is 'Memo3',
  and you are trying to set the value of Delphi side component to the FastReport's component.
  
  In such case, I would write:
  
  [In Delphi]

  procedure TForm1.frxReport1BeforePrint(Sender: TfrxReportComponent);
  begin
    //define and set FastReport variable
    frxReport1.Variables['SomeText'] := '''' + Edit1.Text + '''';
  end;
  

  
  [In FastReport(PascalScript)]

  procedure Page1OnBeforePrint(Sender: TfrxComponent);
  begin
    //refer to FastReport variable
    Memo3.Memo.Text := <SomeText>;
  end;
  

  
  please do not forget to assign event by using report designer.
  
  or directly set to Memo3.Memo by using object inspector of report designer.
  (in this case, the value to set is '[SomeText]' because of variable reference.)
  
  
  if you don't want to use script,

  procedure TForm1.frxReport1BeforePrint(Sender: TfrxReportComponent);
  var
    i: Integer;
  begin
    for i := 0 to frxReport1.ComponentCount-1 do begin
      if (frxReport1.Components[i] is TfrxMemoView) and 
         (TfrxMemoView(frxReport1.Components[i]).Name = 'Memo3') then begin
        TfrxMemoView(frxReport1.Components[i]).Memo.Text := Edit1.Text;
        Break;
      end;
    end;
  end;

  if using the reports onbefore -p0rint event just get the senders hname and cast it to its type to modify it's properties.
  ie
  begin
  if sender.name = 'Memo3' then
  with sender as tfrxmemoview do
  begin
  set any properties here
  sender.memo.text:= 'the text you want';
  end;
  end;
