	Change History (most recent first):

		 <5>	12/14/90	dba		<JDR> get rid of redundant definition of OSTypePtr, now in
									Types.p
		 <4>	 9/18/90	Lai		Change receiptRecord
		 <3>	 9/15/90	Lai		Change AcceptRecord and ReceiptRecord so that they can share the
									same procedure.
		 <2>	 9/10/90	Lai		Remove obsolete constants
		 <1>	  9/7/90	Lai		first checked in
		<0>	  9/7/90	Lai		First Checked in.
