ALl the functions I got from the internet don´t make the CODE128 as requested by the client. Select = + The Array represents the barcode encoded string Select = + Barcorde array assumes 0 as initial offset so we need to add 1 to checksum Now we need to figure out and add the checksum character Select = Loop through our input variable and start pulling out stuff Define the variables that we'll need to be using Define the final holding place of our output string Define the string of characters that we'll need to pull the reference of The last seven characters of Code Sets A and B (character values 96 - 102) and the last three characters of Code Set C (character values 100 - 102) are special non-data characters with no ASCII character equivalents that have a particular significance to the Barcode reading device.A quick google lead me to this solution posted from Dalton from This allows numeric data to be encoded as two data digits per symbol character, at effectively twice the density of standard data. Code Set C (or Chars Set C) includes the set of 100 digit pairs from 00 to 99 inclusive along with three special characters.Code Set B (or Chars Set B) includes all of the standard upper case alphanumeric keyboard characters and punctuation characters along with the lower case alphabetic characters (namely, characters with ASCII values from 32 to 127 inclusive), and seven special characters.alphanumeric keyboard characters and punctuation characters along with the control characters, (namely, characters with ASCII values from 0 to 95 inclusive), and seven special characters. Code Set A (or Chars Set A) includes all of the standard upper case U.S.This symbology includes a checksum digit for verification and the barcode can also be verified character-by-character by verifying the parity of each data byte. Code 128Ĭode 128 is a variable length, high density, alphanumeric, linear bar code symbology capable of encoding full 128-character ASCII character set and extended character sets. The Extended Version can encode all 128 ASCII characters. The Code 93 Extended Barcode symbology is continuous, variable length, and self-checking.
