You could create the alert in another form and then reference it.

You'd use Find_Alert() to get an ID to it, then display it with Show_Alert.

Make the alert a caution and define two buttons and put it in a loop like you are saying. You'll have to use the set_alert_property(alert_id, alert_text, 'your message')
to change the prompt.

like this:

procedure Alert_The_User( MessageText_In IN VARCHAR2,

                                         Failure     IN Boolean := TRUE ) is
  AlertResult    number;
  AlertID        alert;

begin
  AlertID := find_alert( 'MESSAGE_ALERT' );    if NOT id_null( AlertID ) then

      set_alert_property( AlertID, alert_MessageText, messagetext_in );
      AlertResult := show_alert( AlertID );
   else
      bell;
      message( messagetext_in, acknowledge );

  end if;
   if Failure then

       raise FORM_TRIGGER_FAILURE;
   end if;
end;

Maybe you can use the demo code (forms 6i demos) to play a WAV file???
