5Row references are created when dereferencing a <A HREF="c4_Cursor.html" >c4_Cursor</A> or when
6indexing an element of a <A HREF="c4_View.html" >c4_View</A>.  Assignment will change the
7corresponding item.  Rows (objects of type <A HREF="c4_Row.html" >c4_Row</A>) are a special
8case of row references, consisting of a view with exactly one item.

11Internally, row references are very similar to cursors, in fact they are
12little more than a wrapper around them.  The essential difference is one
13of semantics: comparing row references compares contents, copying row
14references copies the contents, whereas cursor comparison and copying
15deals with the pointer to the row, not its contents.
