; ZDB has several locations near the beginning of the program that can
; be changed to alter the operation of the program to suit the user.
;
; You can use Al Hawley's ZCNFG.COM along with the configuration file
; ZDB.CFG to configure many of ZDB.COM's default settings.  As long as
; you retain the default configuration file name at 010Dh, you may
; rename ZDB.COM as you wish, to ADDRESS.COM, for example, and ZCNFG
; will still find the proper overlay file.  The ZCNFG syntax for this
; example would then be:
;
;	A0>ZCNFG ADDRESS
;
; Another method is to edit this configuration overlay file, use your
; favorite assembler to assemble it to a HEX file and use MLOAD or
; MYLOAD to overlay it on ZDB.COM, creating your new working file
; (ADDRESS.COM, for example):
;
;      A0>MLOAD ADDRESS.COM=ZDB.COM,ZDBxxOVL.HEX
;
; When you use this method, you can use the same configuration HEX
; overlay file to quickly configure future versions of ZDB.

; The barcode is composed of full bars and half bars.  Full bars must be
; .115"-.135" (about 1/8") high.  Half bars must be .04"-.06" (about 3/64")
; high.  The barcode is printed in one or two graphics passes, depending on
; the type of printer you are using.
;
; The default graphics strings, below, produce conforming bars on the
; 9-pin Epson MX80 with Graftrax, which requires two passes to produce a
; 1/8" full bar.  The following are the barcode character definitions for
; pass 1.  Each bit represents a printer graphics dot.	Pass 2 prints both
; characters as half bars to provide enough bottom barcode to make full and
; half bars the required height.
;
; Epson LQ-850-compatible 24-pin printers such as the Panasonic KX-P1123 and
; KX-P1124 can produce 1/8" full bars with one pass.  When using a 24-pin
; printer, you may wish to change HBAR, below, to set the last 3 bits and
; change the SETLF length byte, below, to 0 to turn off the second graphics
; pass.
;
fbar:	db	11111111b	; Full bar character (top 8 bits)

; The following are length-prefixed printer strings.  Each string begins
; with a length byte.  Extra space is provided for longer printer codes.
; To eliminate any of these strings, make the first byte 0.  The sample
; codes are for the Epson FX-85:
;
; Printer reset string, sent at start and end of each label/envelope
; printing session.  4 characters maximum:
;
reset:	db	reset0-$-1	; Length byte
	db	esc,'@'		; Reset printer
;
reset0:	ds	reset+5-$,0	; Space for 4 bytes, 0-filled
;
; Set printer for printing return address.  This string is sent to the
; printer after it is reset each time the return address is printed.
; 12 characters maximum:
;
rin:	db	rin0-$-1	; Length byte
	db	0fh		; Set condensed print
	db	esc,'x',1	; Set nlq mode
	db	esc,'p',1	; Set proportional print
;
rin0:	ds	rin+13-$,0	; Space for 12 bytes, 0-filled
;
; Set printer for printing main address.  Cancel any return address
; settings that may require it.  Do NOT use reset, as it will cancel
; the label form length.  12 characters maximum:
;
ain:	db	ain0-$-1	; Length byte
	db	12h		; Cancel condensed print
	db	esc,'E'		; Set emphasized print
	db	esc,'x',1	; Set nlq mode
	db	esc,'p',1	; Set proportional print
;
ain0:	ds	ain+13-$,0	; Space for 12 bytes, 0-filled
;
; Set number of columns for envelope address left margin:
;
lemarg:	db	40		; Start address at column 40
;
; Labels must be at least 3.5" wide to print barcodes, 4" labels are best.
;  With no return address:	 15/16" high minimum (labln=6, llmarg=0)
;  With 3-line return address:	1 7/16" high minimum (labln=9, llmarg=7)
;
; Set number of columns for label address left margin:
;
llmarg:	db	0		; 0 for flush left
;
; Use return address in label (if labels are at least 4" x 1 7/16"):
;
lra:	db	0		; 0 if no return address is desired
;
; Set number of lines per label.  8 characters maximum:
;
labln:	db	labln0-$-1	; Length byte
	db	esc,'C',6	; Set lines per label
;

; address if it appears as the first character in the COMMENTS2 field.
; Any character not often used, such as !@#$%^&~+ is suitable.
;
raflag:	db	'*'
;
; Space from return address to address.  For normal business envelopes,
; the total number of line feeds in the return address and addrsp
; should be 14.  If the number of line feeds in the return address is
; the normal 3, addrsp should be set to 10 lines:
;
addrsp:	db	10
;
; The following string is used to configure your printer to print the
; postal barcode following the address.  The printer must be set to
; print the next buflen (372) bytes in 960 dots/line (120 dots/inch)
; graphics.  Set the length byte to 0 if you don't wish to print
; barcodes.  8 bytes maximum:
;
setgraf:db	setg0-$-1	; Length byte
	db	esc,'L'
	dw	buflen		; Set graphics
;
setg0:	ds	setgraf+9-$,0	; Space for 8 bytes, 0-filled
;
; Most printers will require two passes to print a conforming height
; barcode (see the barcode module, ZDB.C, for barcode definitions.)  The
; following strings are used to change the line spacing for graphics.
; The first pass prints the top 7 dots of the barcode.	The following
; string sets the line spacing to 2 dots to move the paper just enough
; to print the bottom 2 dots.  You might have to adjust it slightly for
; your printer to avoid gaps between dots or overlaps on the bottom of
; the barcode characters.  If your printer will do an conforming barcode
; in one pass, set the following byte to 0 to skip the second pass.
; 8 bytes maximum:
;
setlf:	db	setlf0-$-1	; Length byte
	db	esc,'3',5	; Set linefeed for second pass
;
setlf0:	ds	setlf+9-$,0	; Space for 8 bytes, 0-filled
;
; The following string is used to restore the default line spacing of
; 6 lines/inch.  8 bytes maximum:

	db	esc,'2'		; Restore default line spacing
;
deflf0:	ds	deflf+9-$,0	; Space for 8 bytes, 0-filled

;
; The USPS recommends but doesn't require that the address be printed
