How to type the barcode on item arrival journal --> Line's EAN128/UCC128 field so that it give the item number and quantity?
For example:
Here if I type only 01M0001 and press enter it gives itemId "M0001" in Item number field and if I type only 30100 it gives the "100.00" in Quantity field.
What I want to do is to have item number and quantity together with one entered barcode.
It does not work if I type them together like it is on the picture.
How can I achieve it?
Thanks.
The decoding logic in class BarcodeEAN128, methode decode treats the GTIN (which is identified by the 01 application identifier) as a fixed length field of length 14 (compare to the macro EAN_LEN in the class declaration). Since your ItemId only has 5 characters, the following characters that would define the quantity are treated as part of the ItemId. If you increase the ItemId to 14 characters, it should decode the ItemId and quantity correctly.
See also GS1-128 for a list of application identifiers and their length.
You could try 241M0001+30100 or 241M0001+37100 (where + is a FNC1 character (since 241, 30 and 37 are all variable-length fields). Strictly, 30 and 37 should only be used with 01 or 02 - but these identifiers refer to 14-digit numeric fields.
Another possibility is 95M0001100 where the 5 could be 1 to 5. These are user-defined. Structure them as you will - but don't expect anyone outside of your organisation to understand them.
(strictly EAN-128 as she is designed - no comment on exactly how your application is going to interpret the data. Strictly, 01 and M0001 are incompatible since M0001 is not a valid GTIN)

I am trying to print a GS1-128 Barcode using ZPL and when I print this out for some reason everything prints fine except the number in the AI (37), I get 3715 (the 4 is missing), if I change the 4 to a two char integer value such as 04 or 14 I am able to scan it in the barcode.
^BCN,390,N,N,N
^FD>;>8(02)19410525013094(37)4>8(15)200330>610BAT100^FS
The only issue is the system I am working with stores the value for AI 37 as integers, so if the QTY is 4 then it will print as a 4, but i am getting nothing at the moment.
Any assistance would be appreciated.
Thank you,

You are manually selecting the numeric mode of code128, using >; at the start of the data field. Numeric mode encodes pairs of digits into single codewords. And unfortunately the printer silently drops any unpaired digits.
You must either zero-pad your data when in subset-C or switch to ZPL's automatic mode for code128, which does a good job at minimizing symbol length. For your data, keep the >; start mode and then let the automatic-mode shift or latch to subset-B as needed.
The answer seems to be replacing >8 with >6 for AI 37 to print quantities of single or odd digits! eg 4, 103, etc
I need to generate a GS1-128 barcode using ZPL. It needs to include a check digit. I do not seem to get the check digit.
Here is my code:
^BCN,088,Y,Y,Y,D^FD(00)00123456000057763^FS
The first "Y" is saying to print the human readable along with the
barcode. The third "Y" is supposed to tell it to include a check digit.
I'm not seeing the check digit in the human readable, my scanner is not
displaying a check digit, so I'm assuming it is also not in the barcode?
Here is from the spec:
SSCC Barcode Structure (20 digits)
Application Identifier = (00)
Positions of SSCC barcode:
1 = Extension Digit (0-9 assigned by Vendor)
2 = 0 if mfg id # assigned by GS1 US;
1-9 if mfg id # assigned by another GS1 MO
3 thru 8 = 6-digit mfg id #
9 thru 17 = 9-digit serial id # -must be unique for one year
18 = Modulo 10 check character
TLDR;
^BCN,088,Y,Y,,D
^FD(00)001234560000577630^FS
The third Y does include a Checkdigit, but not the one you want (ZPL Manual, p73):
Mod 103 check digit is always there. It cannot be turned on or off. Mod 10 and 103 appear together with [the third Y] turned on.
When you use D, it will automatically add a checkdigit(ZPL Manual, p80):
The printer automatically
determines if a check digit is required, calculate it, and print it.
But more importantly, it expects you to send 18 digits :
Parentheses and spaces can be in the field data. '00' application identifier, followed
by 17 characters, followed by bogus check digit place holder.
It'll strip out the 18th digit and replace it in both the barcode and the human readable part.

I'd like to generate a GS1-128 barcode like this
(01)5410413901026(17)170612(10)LOT100
in ZPL code
^BY5,3,160^FT372,1506^BCB,,N,N,N
^FD>;>8015410413901026>817170612>810>6LOT100^FS
My problem is the 01 code is normally exactly 14 digits, here my EAN is only 13 digits. So my barcode is misformed.
I have already tried to put >8 at the begin of every new AI without result.
EAN is always 13 digits. Add a leading zero to convert to a 14-digit GTIN. (A digit other than 0 at the start identifies a wholesale container of the item.)

I have verified the barcode from https://zxing.org/w/decode and https://online-barcode-reader.inliteresearch.com/
.proto examples all seem to start numbering their fields at one.
e.g. https://developers.google.com/protocol-buffers/docs/proto#simple
message SearchRequest {
required string query = 1;
optional int32 page_number = 2;
optional int32 result_per_page = 3;
}
If zero can be used, it will make some messages one or more bytes smaller (i.e. those with a one or more field numbers of 16).
As the key is simply a varint encoding of (fieldnum << 3 | fieldtype) I can't immediately see why zero shouldn't be used.
Is there a reason for not starting the field numbering at zero?
One very immediate reason is that zero field numbers are rejected by protoc:
test.proto:2:28: Field numbers must be positive integers.
As to why Protocol Buffers has been designed this way, I can only guess. One nice consequence of this is that a message full of zeros will be detected as invalid. It can also be used to indicate "no field" internally as a return value in protocol buffers implementation.
Assigning Tags
As you can see, each field in the message definition has a unique numbered tag. These tags are used to identify your fields in the message binary format, and should not be changed once your message type is in use. Note that tags with values in the range 1 through 15 take one byte to encode, including the identifying number and the field's type (you can find out more about this in Protocol Buffer Encoding). Tags in the range 16 through 2047 take two bytes. So you should reserve the tags 1 through 15 for very frequently occurring message elements. Remember to leave some room for frequently occurring elements that might be added in the future.
The smallest tag number you can specify is 1, and the largest is 229-1, or 536,870,911. You also cannot use the numbers 19000 through 19999 (FieldDescriptor::kFirstReservedNumber through FieldDescriptor::kLastReservedNumber), as they are reserved for the Protocol Buffers implementation - the protocol buffer compiler will complain if you use one of these reserved numbers in your .proto. Similarly, you cannot use any previously reserved tags.

Just like the document says, 0 can't be detected.
I was reading a Windows DNS server debug log file, in particular the packet captures, and am trying to understand how to parse the host names in order to use them in scripts.
The following is an example from an ANSWER section:
Offset = 0x007f, RR count = 2
Name "[C06A](5)e6033(1)g(10)akamaiedge[C059](3)net(0)"
TYPE A (1)
CLASS 1
TTL 20
DLEN 4
DATA 23.62.18.101
So, looking at the string "[C06A](5)e6033(1)g(10)akamaiedge[C059](3)net(0)" I realized that the numbers in parenthesis are a count of the number of characters that follow. Replacing all of them with dots (except the first and last, which should just be removed) works like a charm.
The stuff in square brackets, though, remains a mystery to me. If I simply remove it all after handling the parenthesis and quotes, the above string becomes e6033.g.akamaiedge.net. That is a valid host name.
So my question is: what does that content in square brackets actually mean? What is the correct way to turn that string into a proper host name I could feed to nslookup and other tools?
It appears it's the 2nd possible form of the NAME field as documented here:
http://www.zytrax.com/books/dns/ch15/#name
NAME This name reflects the QNAME of the question i.e. any may take
one of TWO formats. The first format is the label format defined for
QNAME above. The second format is a pointer (in the interests of data
compression which to fair to the original authors was far more
important then than now). A pointer is an unsigned 16-bit value with
the following format (the top two bits of 11 indicate the pointer
format):
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
1 1
The offset in octets (bytes) from the start of the whole message.
Must point to a label format record to derive name length.
Note: Pointers, if used, terminate names. The name field may consist
of a label (or sequence of labels) terminated with a zero length
record OR a single pointer OR a label (or label sequence) terminated
with a pointer.
where the response is using pointers to refer to data elsewhere in the message.
