Since it's been nearly a week since I asked this question, with no response, 
here it is again....
Thanks again for any help - I actually am interested in the answer.

-------------------

Seems the typical event handler works by using something like (borrowed from 
http://onboardc.sourceforge.net/cookbook.html ): 
======================= 
static Boolean 
appHandleEvent (EventPtr pEvent) 
{ 
FormPtr pForm; 
Int16 formId; 
Boolean handled = false; 

if (formId == MainForm) 
FrmSetEventHandler (pForm, mainFormEventHandler); 

// *** ADD NEW FORM HANDLING HERE *** // 
etc, etc...... 

} 
====================== 

Then, in the "mainFormEventHandler" code: 



======================= 
static Boolean 
mainFormEventHandler(EventPtr pEvent) 
{ 
Boolean handled = false; 
FormPtr pForm = FrmGetActiveForm(); 
switch (pEvent->eType) 
{ 
etc., etc.,........ 

} 
======================= 

MY QUESTION: Why isn't the active form pointer passed in to 
"mainFormEventHandler(...)" by the calling function [somewhere inside of 
FormDispatchEvent() possibly]. This would make sense, because the association 
between the handler and the pointer to the form was already established during 
execution of 
appHandleEvent(...). 

Is it slower to do that (use the stack)? Did Palm, Inc., just want to be free 
to hide the implementation of the form-to-handler association?? 

Thanks!
