RollCredits NBA 2.3, by Michael O'Keefe

This NBA allows you to automatically scroll the
contents of a text field.

You can also call this NBA from a scripting language like HyperLogo. The parameters you have to pass to RollCredits are the name of the field, how many steps, how fast, and how many pixels to scroll each time.  As an example, if you wanted to scroll a field named “fred”, twenty steps, at a speed of  5 (pretty fast), and scroll 3 pixels at a time you could use the following HyperLogo line:

CallNBA “RollCredits “fred\ 20\ 5\ 3  4

(the “4” above is the “Run” message you send to NBAs)
