YesNo is using the internal page named "WEBDEVYesNo". To include this page in your project:
  1. Select "File .. New .. Page".Click among the quick access buttons. Click "Page" in the wheel that is displayed. The window for creating a new element is displayed: click "Page" then "Page".

YesNo("The XXX form was modified." + CR + ...
"Do you want to save it before exiting?")
is equivalent to:
YesNo("The XXX form was modified.", ...
"Do you want to save it before exiting?")
