Apparently, p->csParam is declared as an array of shorts.  There is, however,
a clearer way to get an EventRecord pointer out of this:

	*(EventRecord **)&p->csParam

is slightly clearer than

	(EventRecord *) * (long *) &p->csParam 

and should do the same thing.  You have to use the '&' operator, since otherwise
p->csParam will extract a 16 bit quantity.
