The Device Manager section of IM defines three things of importance
to the GoodBye kiss feature:

	dCtlFlags - a word at offset 4 in the device control entry
	drvrFlags - a word at offset 0 in the driver header
	dNeedGoodBye - bit number 4 for usage in bit munger
		calls or 16 for direct operations.

In order to receive a good bye kiss when an application goes away
set the dNeedGoodBye bit in dCtlFlags.  THis can be done at run
time with:
	dce->dCtlFlags |= dNeedGoodBye
or
	BitSet(@dce^.dCtlFlags, LONGINT(dNeedGoodBye))
or by setting it in the header, however you happened to get that
defined.

Having done so your Control routine will be called with csCode
equal to -1 when the application heap is about to be reinitialized,
which happens mainly when an application is Launched.  Exiting
an application is really Launching the Finder so it works as
expected.

I will now refrain from the usual exhortation to buy a copy of
Inside Macintosh if you plan on doing any programming of the mac.

If the pascal function call is incorrect please forgive me as it
has been quite a few years since I gave it up.
