Description
The maxscroll property tells us the largest allowed scroll value for a text field. It represents the number of the last line in a text field that can be used as the top line in its viewable region. In Flash 4 and Flash 5, the maxscroll property is used with the scroll property to manage a scrolling-text field. As of Flash 6, maxscroll is formalized as a property of the TextField class, TextField.maxscroll.
