>Where did you find information on this? Surely not in the included documentation! I have read and studied almost all of the 400+ developer's guide, OOP guide, and the Jumpstart Guide and only the APPINCL.H file rings a bell. And, the only definition I can find about the A, C, and K classes is a blurb on page 39 ("Summary of Framework Libraries") and it is not very helpful to me at all.

Hi Paul,

It's passed down from one user generation to the next in the Oral Tradition of the Great Mere Mortal.

The elders council had decided that your time had arrive and the information was now passed down to you.

OK, seriously, this sort of thing is usually learned by experience and by actually delving into the classes find their mojos and learn what makes them tick.

Once you're past it, you will forget to write it down or tell Kevin about it so it's included in the next version of the docs.

If you are curious enough (and you seem to be), you will find yourself tracing through the class code quite often and saying to youself "gee, this is neat!", or "What did just happen here?!?!?!?." It's a process of discovery. Enjoy it!!!
