Implements a virtual function to compare two bookmarks.

function CompareBookmarks(Bookmark1, Bookmark2: TBookmark): Integer; virtual;

As implemented in TDataSet, CompareBookmarks always returns 0, indicating no difference between the bookmarks. This is because TDataSet does not implement support for bookmarks.

Descendant classes that provide bookmark support override this method to return a value less than 0 if Bookmark1 is less than Bookmark2, 0 if the bookmarks are identical, and a value greater than 0 if Bookmark1 is greater than Bookmark2.
