Why does the online barcode font encoder for Code 128 and UCC 128 give different results


I am testing data for use with the IDAutomationC128 barcode font. We are trying to get the correct data for use on packages for the USPS. The data we are testing is 42060091Ê93789107596195121000000012
the Code 128 gives the encoded result of ÍJ&Â{Ê}n{'[]Ã,*ÂÂÂ,iÎ
the UCC Code 128 gives the encoded result of ÍÊJ&Â{Ê}n{'[]Ã,*ÂÂÂ,'Î

the UCC Code 128 seems to be the correct one. However manually verifying this results in the MOD 103 check digit value of 73 which is the code 128 result.

Any insight will be appreciated.

Best Answer

What encoder are you using? The UCC function includes the FNC using Ê. With the Code 128 function, it does not include the FNC. Therefore, to encode it, you will have to insert it on your own.

Here is the issue I am having when using the online encoder on the IDAutomation site
http://www.bcgen.com/fontencoder/Default.aspx

the data to encode is Ê42060091Ê93789107596195121000000010 encoding the following
ÍÊJ&Â{Ê}n{'[]Ã,*ÂÂÂ*hÎ ok great. check value of 72 which "h" is the MOD 103 check digit and i have data to put into my recently purchased font.

oops. we need to calculate the MOD 103 check digit manually here. Using the example provided on the site https://www.idautomation.com/barcode-faq/code-128/#Creating_GS1-128 under example how to calculate the check character for Character Set C

The following table is an example of how to obtain the check character for the number "667390" using character set C.

Start C 66 73 90 STOP
weighting 1 2 3
values 105 66 73 90
totals 105 66 146 270
Separate the numbers into pairs and choose the appropriate character from the character set table that represents the number pair.
Calculate the Total: 105 + (66*1) + (73*2) + (90*3) = 587
Calculate the Checksum: 587 divided by 103 = 5 remainder of 72. Therefore, the check digit equals a value of 72. The character to print for the value of 72 is ASCII 104.
To print the data "667390" as a barcode, the text of ÍbizhÎ is combined with the Code 128 Barcode Fonts.

Using the data we have to manually cacluate the check digit. Ê42060091Ê93789107596195121000000010 along with the example the check digit value is 38 which is code C value of "F" NOT the result as the online encoder

Is there something we are missing?

thanks Ben. We will give it a try.

If you need to use the Online Font Encoder, you can encode the FNC using parentheses. Though we do not have full COBOL encoder source, you may want to look at our VBA code and convert it to COBOL.

As a guide, you might be able to use this COBOL encoder (created by a customer):

CALCULATE-CHECK-SUM.
MOVE ZEROS TO BAR-CHECK-SUM.
MOVE 104 TO BAR-CHECK-SUM.
MOVE JOB-ID TO WS-BAR-JOB-ID.
PERFORM VARYING BAR-SUB FROM 1 BY 1 UNTIL BAR-SUB > 14
IF BAR-SUB < 14
IF BAR-SUB = 9
COMPUTE BAR-STR-NUM = 47 - 32 FOR THE /
COMPUTE BAR-CHECK-SUM = BAR-CHECK-SUM +
(BAR-STR-NUM * 9)
END-IF
IF BAR-SUB < 9
IF BAR-JOB-ID(BAR-SUB) = 0 FOR THE MAIN JOB
MOVE 16 TO BAR-JOB-NUM
ELSE
COMPUTE BAR-JOB-NUM = BAR-JOB-ID(BAR-SUB) + 48 - 32
END-IF
COMPUTE BAR-CHECK-SUM = BAR-CHECK-SUM +
(BAR-JOB-NUM * BAR-SUB)
END-IF
IF BAR-SUB = 10
COMPUTE BAR-SUB-1 = BAR-SUB - 1 FOR THE FIRST DIGIT OF SUB JOB
IF BAR-JOB-ID(BAR-SUB-1) = 0
MOVE 16 TO BAR-JOB-NUM
ELSE
COMPUTE BAR-JOB-NUM = BAR-JOB-ID(BAR-SUB-1) +
48 - 32
END-IF
COMPUTE BAR-CHECK-SUM = (BAR-CHECK-SUM +
(BAR-JOB-NUM * BAR-SUB))
END-IF
IF BAR-SUB = 11
COMPUTE BAR-SUB-1 = BAR-SUB - 1 FOR THE SECOND DIGIT OF SUB JOB
IF BAR-JOB-ID(BAR-SUB-1) = 0
MOVE 16 TO BAR-JOB-NUM
ELSE
COMPUTE BAR-JOB-NUM = BAR-JOB-ID(BAR-SUB-1) +
48 - 32
END-IF
COMPUTE BAR-CHECK-SUM = (BAR-CHECK-SUM +
(BAR-JOB-NUM * BAR-SUB))
END-IF
IF BAR-SUB = 12
COMPUTE BAR-SUB-1 = BAR-SUB - 1 FOR THE SPACE
* IF BAR-JOB-ID(BAR-SUB-1) = 0
* MOVE 16 TO BAR-JOB-NUM
* ELSE
* COMPUTE BAR-JOB-NUM = BAR-JOB-ID(BAR-SUB-1) +
* 48 - 32
* END-IF
* COMPUTE BAR-CHECK-SUM = (BAR-CHECK-SUM +
* (BAR-JOB-NUM * BAR-SUB))
END-IF
IF BAR-SUB = 13
COMPUTE BAR-STR-NUM = PART + 48 - 32 FOR THE PART
COMPUTE BAR-CHECK-SUM = BAR-CHECK-SUM +
(BAR-STR-NUM * 13)
END-IF
END-IF
END-PERFORM.
DIVIDE 103 INTO BAR-CHECK-SUM GIVING BAR-RESULT
REMAINDER BAR-REMAINDER.
IF BAR-REMAINDER = 0 MOVE "Â" TO PRT-VALUE CALCULATE THE CHECK SUM
ELSE IF BAR-REMAINDER = 1 MOVE "!" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 2 MOVE '"' TO PRT-VALUE
ELSE IF BAR-REMAINDER = 3 MOVE "#" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 4 MOVE "$" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 5 MOVE "%" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 6 MOVE "&" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 7 MOVE "'" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 8 MOVE "(" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 9 MOVE ")" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 10 MOVE "*" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 11 MOVE "+" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 12 MOVE "," TO PRT-VALUE
ELSE IF BAR-REMAINDER = 13 MOVE "-" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 14 MOVE "." TO PRT-VALUE
ELSE IF BAR-REMAINDER = 15 MOVE "/" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 16 MOVE "0" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 17 MOVE "1" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 18 MOVE "2" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 19 MOVE "3" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 20 MOVE "4" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 21 MOVE "5" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 22 MOVE "6" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 23 MOVE "7" TO PRT-VALUE
ELSE IF BAR-REMAINDER = 24 MOVE "8" TO PRT-VALUE

Using the online encoder from IDAutomation website http://www.bcgen.com/fontencoder/Default.aspx

checking it manually using the MOD 103 Calculation Example for Character Set C, a value of 73 which is the code 128 result of i

we here will have to calculate the value manually. we use COBOL programming here and as far as we know there is no other way to calculate it using COBOL.
