Flash Lite supports the TextField.scroll and TextField.maxscroll properties, which let you create scrolling text fields. The scroll property specifies the first visible line in a text block; you can get and set its value. For example, the following code scrolls the text field whose variable name is story_text down by five lines:

story_text.scroll += 5;

The maxscroll property specifies the first visible line in a text block when the last line of the text is visible in the text block; this property is read-only. You can compare a text field's maxscroll property to its scroll property to determine how far a user has scrolled within a text field. This is useful if you want to create a scroll bar that provides feedback about the user's current scroll position relative to the maximum scroll position.
