;		 <3>	 5/21/91	gbm		Nail a couple of warnings
;		 <2>	 1/30/91	gbm		sab, #38: Change the ‘already including this file’ variable to
;									all uppercase (for security reasons)
;		<1>		 1/18/91	mbs		(jg) First moved to BBS
;		<12>	 1/10/91	mjq		Add 'AddCSCode' and 'AddCSAddr' with Undefined checking for BBS.
;		<11>	 1/08/91	mjq		Add UNDEFINED checking on CancelAtalkClosePrep.
;		<10>	 1/08/91	mjq		Add some UNDEFINED checking. Include MPPmacros2.a
;		 <8>	12/21/90	mbs		Add transition queue event codes for NBP name change
;		 <7>	12/13/90	mbs		Add new csCode for stalling when opening .MPP
;		 <6>	11/28/90	mbs		Add Transition Queue equate for network transition
;		 <5>	10/31/90	mbs		Add more things to the 976 call
;		 <4>	10/23/90	mbs		Add new .MPP control code to get 976 hooks
;		 <3>	10/16/90	mbs		Move more private stuff from AtalkEqu.a
