:This tells me that after the WaitPort call, message will point to the
:first message in the list.  The funny thing is that when I do a GetMsg(port)
:I get a different address, although it also is listed as returning a pointer
:to the first message in the port's message list.  What's going on here?
:I wanted to see if I could do just the following:
:
:	message = WaitPort(port);
:	code = message->Code;
:	class = message->Class;
:	ReplyMsg(message);

	WaitPort() does NOT remove the message from the port.  you should
NEVER ReplyMsg() without GetMsg() it first.  I.E.:

	WaitPort(port);
	message = GetMsg(port);
 	code = message->Code;
 	class = message->Class;
 	ReplyMsg(message);
