integer AIT_VerifyCount  (
  string strCaption,     // Control's caption
  integer nCtrlType,     // Control type
  integer nItemCount     // Item count
);
integer AIT_VerifyCount  (
  integer nCtrlID,       // Control ID
  integer nCtrlType,     // Control type
  integer nItemCount     // Item count
);
