I´m having the same problem. But I have to access the datebook.dat

The info in http://www.geocities.com/Heartland/Acres/3216/datebook_dat.htm
helps me to program for 4.0.x version of palm desktop, and works fine.

I can´t find the data structure of the .DAT files for 4.1.x versions.

Anyone can help us ? doesn´t matter the programming language

(excuse me for my english)
