GS1 Compound Barcodes or FDA Compound Barcodes
NOTE: this mod was written for one customer and I was asked to make it standard afterwards, this means "NOT EVERY" GS1 data identifier is accounted for, so this mod may not work with every GS1 barcode without more programming.
Description: GS1 barcodes contain data identifiers that indicate what the next string of data is in the barcode, and that is how we know what you do with the compound data.
Example: (01) at the beginning indicates the next 14 char. are the Item number.
