Way can't make it work in next code?
procedure TForm2.Beri(Ime:string);
    var
          podatki1: textfile;
          vrstica: string;
  begin
     AssignFile(podatki1,Ime);
     Reset(podatki1);
     While not EOF (podatki1) do begin
     ReadLn(podatki1,vrstica);
     F.Memo1.Lines.Add (vrstica);
     end;
 
     F.  memo1.SelStart := length(memo1.Text);
     F.memo1.Perform(EM_ScrollCaret,0,0);
     CloseFile(podatki1);
 
  end;
