Sample coding 4:

CD.Data$=CHKDGT$("a123Qa","N")

"Q" is a CD position character, so CHKDGT$ calculates the

correct CD and

CD.Data$ will become "-."

■ When

CDtype is A (EAN or UPC), CHKDGT$ identifies the EAN or UPC of

barcodedata depending upon the data length (number of digits) as listed

below.

If the data length is a value other than 13, 8, and 7, this function returns a null

string.

- To check that the CD is correct:

Pass a CD-suffixed

barcodedata to a CHKDGT$ as shown below. If the

returned value is equal to the CD, the CD data is suitable for the

barcodedata.

Sample coding:

IF CHKDGT$("49400458","A")="8"

THEN...

- To add a CD to barcode data:

Pass barcodedata followed by a dummy character to a CHKDGT$ as shown

below. The returned value will become the CD to be replaced with the dummy char-

acter.

Sample coding:

PRINT"4940045"+CHKDGT$("4940045"+"0","A")

■ When CDtype is H (STF), the length of barcodedata must be two or more

digits. If not,

CHKDGT$ returns a null string.

- To check that the CD is correct:

Pass a CD-suffixed

barcodedata to a CHKDGT$ as shown below. If the

returned value is equal to the CD, the CD data is suitable for the

barcodedata.

Sample coding:

IF CHKDGT$("12345678905","H")="5"

THEN...

- To add a CD to barcode data:

Pass barcodedata followed by a dummy character to a CHKDGT$ as shown

below. The returned value will become the CD to be replaced with the dummy char-

acter.

Sample coding:

"1234567890"+CHKDGT$("1234567890"+"0"."H")
