Row references are created when dereferencing a c4_Cursor or when indexing an element of a c4_View. Assignment will change the corresponding item. Rows (objects of type c4_Row) are a special case of row references, consisting of a view with exactly one item.

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.
