*   List Node Structure.  Each member in a list starts with a Node

   STRUCTURE	LN,0	; List Node
	APTR	LN_SUCC	; Pointer to next (successor)
	APTR	LN_PRED	; Pointer to previous (predecessor)
	UBYTE	LN_TYPE
	BYTE	LN_PRI	; Priority, for sorting
	APTR	LN_NAME	; ID string, null terminated

** Note: Newly initialized IORequests, and software interrupt structures
** used with Cause(), should have type NT_UNKNOWN.  The OS will assign a type
