function TMainForm.GetDataStrings2(FileName: string; DataList: TStringList): boolean;
var F: TextFile;
    s: string;
    APos, BPos: integer;
begin
  AssignFile(F, FileName);
  Reset(F);
  While not EOF(F) do
   begin
    ReadLn(F, s);
    If s[Length(s)] <> ',' Then s := s + ',';
    APos := Pos('=', s);
    If APos > 0 Then
     begin
      While (s[APos] <> ' ') do APos := APos - 1;
      APos := APos + 1;
      s := Copy(s, APos, Length(s));
      While Length(s) > 0 do
       begin
        BPos := Pos(',', s);
        DataList.Add(Copy(s, 0, BPos - 1));
        Delete(s, 1, BPos + 1);
       end;
     end;
   end;
  CloseFile(F);
  Result := DataList.Count > 0;
end;
