;MACRO TO DEFINE A DATA STRUCTURE FOR A GIVEN FIELD.
; CALL IS:	FIELD.(NAME,WIDTH,POSITION,<OPTIONAL VALUE>,<OPTIONAL LOCATION>
; ARGUMENTS:
;	NAME		SIX CHARACTER DATA STRUCTURE NAME
;	WIDTH		SIZE OF FIELD IN BITS.
;	POSITION	POSITION OF RIGHTMOST BIT OF FIELD, DECIMAL
;	VALUE		OPTIONAL, IF SPECIFIED WILL GENERATE A LOCATION
;			  IF USED WITH EWORD., WITH VALUE "VALUE".
;	LOCATION	OPTIONAL, IF SPECIFIED WILL GENERATE A LOCATION
;			  IF USED WITH EWORD., WITH "VALUE"
;			  AS THE CONTENTS
;
; FIELDS OF GREATER THAN LENGTH 1 (BYTE MASKS) CALL DEFST. TO DEFINE
; A MACRO THAT CAN BE USED WITH LOAD./STOR.
;
; FIELDS OF LENGTH 1 DO NOT USE DEFST., BUT DIRECTLY ASSIGN THE 36
; BIT VALUE OF THE BIT POSITION TO THE SYMBOL "NAME".  THIS IS BECAUSE
; THE "TX" MACROS CANNOT BE USED, BECAUSE THEY DO NOT HANDLE EXTERNAL
; SYMBOLS CORRECTLY AND WOULD HAVE TO BE MIXED WITH REGULAR TEST INSTRUCTIONS.
; THEREFORE, DO NOT USE LOAD./STOR. FOR SINGLE BIT VALUES! USE LOAD./STOR.
; TO FETCH THE WORD, AND DO A REGULAR TEST INSTRUCTION USING THE BIT
; VALUE. IF THE VALUE IS IN THE LEFT HALF, USE "()" TO SWAP IT.
; ALTERNATIVELY, ONE CAN DEFINE WORD NAMES (EXAMPLE, ETDSTS) IN ORDER
; TO DO "TDXX" INSTRUCTIONS.
;
; THE SYMBOL ZZ00 (LEVEL 0, TEMP SYMBOL 0) IS USED TO ACCUMULATE
; VALUES FOR A GIVEN WORD. THE MACRO EWORD. WILL CAUSE THESE ACCUMULATED
; VALUES TO BE PLACED IN A LOCATION. IF NO FIELD. MACRO GENERATED A VALUE
; FOR THE CURRENT WORD, THEN EWORD. WILL GENERATE A "BLOCK 1". SEE
; THE EWORD. MACRO FOR FURTHER DETAILS.
