Row references are created when dereferencing a <A HREF="c4_Cursor.html" >c4_Cursor</A> or when
indexing an element of a <A HREF="c4_View.html" >c4_View</A>. Assignment will change the
corresponding item. Rows (objects of type <A HREF="c4_Row.html" >c4_Row</A>) are a special
case of row references, consisting of a view with exactly one item.
<P>
Internally, row references are very similar to cursors, in fact they are
little more than a wrapper around them. The essential difference is one
of semantics: comparing row references compares contents, copying row
references copies the contents, whereas cursor comparison and copying
deals with the pointer to the row, not its contents.
