Description
Frees the resources allocated for a specified bookmark (somewhat obsolete).
TBookmark is an alias of TBytes. This means that TBookmark is automatically garbage collected when it goes out of scope. Because TBookmark does not need to free memory, the FreeBookmark method is blank for the default implementation.
If a TDataSet descendant still needs to free resources allocated when using bookmarks, the FreeBookmark method should be overridden to a specific functionality when the bookmark is no longer needed. Otherwise, you do not need to use this method.
