UPDATE updates the contents of the list box objects, i.e. the function <set> (see LIST BOX - CREATE (AES 170)) is called for each of the objects. If <rect> is not 0L it will be regarded as a pointer to a GRECT that will be used for the redraw of the list box. Otherwise the objects will only be updated but not drawn.
