  in a method called using Synchronize, for example,

      Synchronize(UpdateCaption);

  and UpdateCaption could look like,

    procedure tSender.UpdateCaption;
    begin
      Form1.Caption := 'Updated in a thread';
    end; }

{ tSender }

procedure tSender.Execute;
begin
  { Place thread code here }
  repeat
   inc(Form1.s);
   if form1.f>form1.n then
    form1.f:=1;
   form1.a[form1.f]:=n;
   sleep(slp);
  until terminated;
end;
