>I heard from someone at DevCon96 that there is a 20-page document on using CODEBOOK 3.0.

Asif,
I remeber it was available from the foxuser forum in Compuserve
(when I still had a CIS account )
also you can probaly find it in flash's Internet site
(I think I remeber seeing it once)
if you can't find it email me directly and I'll send a copy to you
