; NOTE: the next 13 bytes (up to BMenu, below) MUST remain in 
;  the following locations:

	rst	0	; For safety, so .CFG file won't execute

	dw	AMenu	; For relocation of addresses, this
			; ..points to the NEXT location.

; ---------------------------------------------------------
;
;	MENU LIST SECTION
;
; Each entry is a doubly linked node, pointing to the next entry
;  in the list, the previous entry in the list, and a menu screen, 
;  case table, and help screen.  If only one menu is to be used,
;  it points only to itself.

AMenu:	dw	AMenu, AMenu, AScrn, ACase, AHelp	; Entry for menu A

; -------------------------------------
;
;	CASE TABLE SECTION
;
; Case table for Menu A.  The first two bytes give the number of
;  records followed by the length of each record.  The rest of the table
;  consists of up to 255 identical records.

ACase:	db	(ACaseX-ACase1)/(ACase2-ACase1)	; Number of cases
	db	ACase2-ACase1			; Length of each record

ACase1:
	db	'D'	; Unique ASCII selector from SCREEN IMAGE
	dw	DecRad	; ZCNFG function number
	dw	drive	; Location in file to be patched by ZCNFG
	db	1	; Number of bytes for ZCNFG to change
	dw	AScrnD	; Location to change in SCREEN IMAGE
	dw	AC1MM	; 0 or address of min/max data words or strings

ACase2:
	db	'U'	; Unique ASCII selector from SCREEN IMAGE
	dw	DecRad	; ZCNFG function number
	dw	user	; Location in file to be patched by ZCNFG
	db	1	; Number of bytes for ZCNFG to change
	dw	AScrnU	; Location to change in SCREEN IMAGE
	dw	0	; 0 or address of min/max data words or strings

ACase3:
	db	'N'	; Unique ASCII selector from SCREEN IMAGE
	dw	Text	; ZCNFG function number
	dw	FName	; Location in file to be patched by ZCNFG
	db	8	; Number of bytes for ZCNFG to change
	dw	AScrnN	; Location to change in SCREEN IMAGE
	dw	0	; 0 or address of min/max data words or strings

ACase4:
	db	'T'	; Unique ASCII selector from SCREEN IMAGE
	dw	Text	; ZCNFG function number
	dw	FType	; Location in file to be patched by ZCNFG
	db	3	; Number of bytes for ZCNFG to change
	dw	AScrnT	; Location to change in SCREEN IMAGE
	dw	0	; 0 or address of min/max data words or strings

ACase5:
	db	'P'	; Unique ASCII selector from SCREEN IMAGE
	dw	ToglTF	; ZCNFG function number
	dw	PFlag	; Location in file to be patched by ZCNFG
	db	1	; Number of bytes for ZCNFG to change
	dw	AScrnP	; Location to change in SCREEN IMAGE
	dw	AC5St	; 0 or address of min/max data words or strings
ACaseX:			; Label for calculation of list length

; Case table support data structures.

AC1MM:			; Min/Max for ACase1, above
	dw	0	; Min (0=default drive)
	dw	16	; Max (16=drive P)

AC2MM:			; Min/Max for ACase2, above
	dw	0FFh	; Min (0FFh=default user)
	dw	32	; Max user

AC5St:			; Strings for ACase5, above
	db	'YES',0
	db	' NO',0

;
;	SCREEN IMAGE SECTION

; Sample screen image for Menu A.  This is what appears on the screen
;  when the user initially invokes ZCNFG with this .CFG file.  This screen
;  data is pointed to by its MENU LIST entry (above).  Before displaying
;  the following ASCII information, ZCNFG substitutes the current values
;  for the file being altered for the blank spaces at the secondary labels
;  below.

AScrn:
	db	cr,lf,lf,tab,tab,tab,'Note Taker Installation Menu'
	db	cr,lf,lf

	db	tab,'D) Default output drive  (0..16; 0 = current) ........ '
AScrnD:	db	'   '			; Display current value here
	db	cr,lf,lf

	db	tab,'U) Default output user area (0..32; 255 = current) ... '
AScrnU:	db	'   '			; Display current value here
	db	cr,lf,lf

	db	tab,'N) Default output filename ...................... '
AScrnN:	db	'        '		; Display current value here
	db	cr,lf,lf

	db	tab,'T) Default output filetype ........................... '
AScrnT:	db	'   '			; Display current value here
	db	cr,lf,lf

	db	tab,'P) Prompt for filespec on exit ....................... '
AScrnP:	db	'   '			; Display current value here
	db	cr,lf,lf

	db	lf,lf,lf,lf		; Fill rest of screen

	db	0			; Terminator

;
;	HELP SCREEN SECTION
;

; Help screen for Menu A.  The following, up to the terminating
;  binary 00, appears as-is when the user types "?" or "/" for help while
;  ZCNFG is displaying the initial patch menu.
