/* 
	Important note about TEClickLoopProcPtr and WordBreakProcPtr

	At one point these were defined as returning the function result in the 
	condition code Z-bit.  This was correct, in that it was what the 68K
	implementation of TextEdit actually tested.  But, MixedMode had a different 
	idea of what returning a boolean in the Z-bit meant.  MixedMode was setting
	the Z-bit the complement of what was wanted.  
	
	Therefore, these ProcPtrs have been changed (back) to return the result in
	register D0.  It turns out that for register based routines, 
	MixedMode sets the Z-bit of the 68K emulator based on the contents 
	of the return result register.  Thus we can get the Z-bit set correctly.  
	
	But, when TextEdit is recoded in PowerPC, if it calls a 68K ClickLoop
	or WordBreak routine, register D0 had better have the result (in addition
	to the Z-bit). Therefore all 68K apps should make sure their ClickLoop or
	WordBreak routines set register D0 at the end.
*/

/* 
	There is no function to get/set the low-mem for FindWordHook at 0x07F8.
	This is because it is not a low-mem ProcPtr. That address is the entry
	in the OS TrapTable for trap 0xA0FE.  You can use Get/SetTrapAddress to 
	acccess it.
