Try the following on OnChange event of memo:

procedure TtForm1.Memo1Change(Sender: TObject);
var ro, co: Integer;
begin
  ro := Memo1.Perform(EM_LINEFROMCHAR, Editor.SelStart, 0); //this is the row
  co := Memo1.SelStart - Editor.Perform(EM_LINEINDEX, ro, 0); // this is the col
  Form1.Caption :=  Format('Row: %d, Col %d', [ro + 1,co + 1]);//row col is 0 based
end;

Regards,
Igor
