The prevalent use of this technique throughout the early Palm OS source code and samples lead me to believe that the author just didn't know about offsetof. It was only in later versions of the OS and SDK (around Palm OS 3.5, I think) that the OffsetOf macro was added and used. -- Keith -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
