(Maitre'D 2002, and later versions of Maitre'D)

Accounts Receivable

Track 2 is the supported track. The customer code can be up to eight (8) alphanumeric characters and every character is associated to a specific number that you will find in the following chart.

A=35	N=48	a=67	n=80	0=18
B=36	O=49	b=68	o=81	1=19
C=37	P=50	c=69	p=82	2=20
D=38	Q=51	d=70	q=83	3=21
E=39	R=52	e=71	r=84	4=22
F=40	S=53	f=72	s=85	5=23
G=41	T=54	g=73	t=86	6=24
H=42	U=55	h=74	u=87	7=25
I=43	V=56	i=75	v=88	8=26
J=44	W=57	j=76	w=89	9=27
K=45	X=58	k=77	x=90
L=46	Y=59	l=78	y=91
M=47	Z=60	m=79	z=92

The formula that was used to set this chart is:
ASCII value of the character - 30 = number use
If the result is lower then 0, number use = 02
Example
With the customer code number 1234
;<<1920212202020202>>00000000000000000?

;	start code
<<	start code delimiters
19	1
20	2
21	3
22	4
02	blank from the customer code
02	blank from the customer code
02	blank from the customer code
02	blank from the customer code
>>	end code delimiters
00000000000000000	not use but needed
?	end code

Maitre'D use only the first 16 digits but you need to have all the string.
