programming the dial and button box

[Brent Thomas Corkum]

I'm wondering how easy it is to write a program that uses input from
the dial and button box. We have one and use it extensively with IDEAS, 
but we haven't tried to incorporate it into any of our home brew packages.
If anyone has experience with writing code for the dial and button box
can you tell me what I need to do and if you can include a short snipit 
of code it would be much appreciated.
