Make dynamic or input text fields scrollable by using menu commands or the text field handle.

Add a ScrollBar component to a text field to make it scroll. For more information, see “UIScrollBar Component” in the ActionScript 2.0 Components Language Reference.

In ActionScript, use the TextField object’s scroll and maxscroll properties to control vertical scrolling and the hscroll and maxhscroll properties to control horizontal scrolling in a text field. See Example: Creating scrolling text in Learning ActionScript 2.0 in Adobe Flash.
