  This is code from my project:
  In Delphi (I use FIBPlus dataset)

  procedure TMainForm.ChangeLimitZaborSort;
  var fields :TStringList;
      ordering: array of Boolean;
  begin
       fields:=TStringList.Create;
       fields.Add('NOMER');
       fields.Add('KOD');
       fields.Add('PRICE_REALIZ');
       SetLength(ordering,3);
       ordering[0]:=true;
       ordering[1]:=true;
       ordering[2]:=true;
       MainDM.TableLimitZabor.DoSortEx(fields,ordering);
       fields.Free;
  end;
  
  function TMainForm.Report_3UserFunction(const MethodName: String;
    var Params: Variant): Variant;
  begin
       if MethodName='CHANGELIMITZABORSORT' then
       ChangeLimitZaborSort;
  end;
  

  in report script:
  

  procedure Button1OnClick(Sender: TfrxComponent);
  begin
       if CheckBox1.Checked then ChangeLimitZaborSort;
  end;
