Q1: I have been staring blankly at the section titled "Data Structures
Within Apple Events" in IM Chap. 6 with the hope of understanding
where one might use AEPutKeyDesc as opposed to AEPutParamDesc. What
good is an AERecord. Can anyone give a scenario for the use of
AEPutKeyDesc? (I use AEPutParamDesc all the time.)
Q2: What is the difference between required and optional event parameters?
I don't see any way to specify that a given parameter one is adding to
an AppleEvent is optional. For example, take the Close event: the
parameter keyAESaveOptions is supposed to be optional but if I include
it then the receiving program had better have read it before it calls
it's GotRequiredParams function. i.e., it doesn't appear to be very
optional to the receiver. Am I missing something?
Q3: Where is it documented that Apple Events are limited to 64 KB of data?
Thanks,
Larry Hutchinson
