Former Member — Wed, 26 Jul 2006 15:29:26 GMT

HI All,

Pls write a simple code for me.

0=0

1=1

2=2

3=3

4=4

5=5

6=6

7=7

8=8

9=9

A=10

B=12

C=13

D=14

E=15

F=16

G=17

H=18

I=19

J=20

K=21

L=23

M=24

N=25

O=26

P=27

Q=28

R=29

S=30

T=31

U=32

V=34

W=35

X=36

Y=37

Z=38

Use modulus 11 and remindr is check digit

Example

EIMU466000

15*1+

19*2+

24*4+

32*8+

4*16+

6*32+

6*64+

0*128+

0*256+

0*512

=1045/11=95 and reminder is 0 check digit is 0

When 11th digit enter by customer .It has to veryfy the above logic & check the riminder.

For incorrect entry Pass the error message.

Thanks in advance,

Singha

HI,

Please try following logic

var1 = 'EIMU466000'.

var = strlen(var1).

do var times.

var2 = var1+var(1).

case var2.

when '0'

sum = sum + 0 * var.

when '1'

sum = sum + 1 * var

when.....(use all digits)

endcase.

enddo.

sum1 = sum /11.

if sum1 > 0.

message .....

endif.

Amole
