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?
