Issue manually calculating checksum for Code 128


I'm not programming in one of the supported languages, so I had to write my own encoder and checksum calculator. In general, things are working except for at least one case 00000.

I start with Code 128 subset C and calculate the same string (ÍÂÂÈ0YÎ) as the IDAutomation Free Online Font Encoder Tool except for the checksum. I come up with ÍÂÂÉ0Î instead. I.e. I get a check digit calculation result of 60 vs 57.

This is rather urgent. Could someone walk through this calculation?


Application: TCL

Best Answer

IDAutomation cannot provide implementation support for manual encoding, as it is outside the scope of support.

What can be suggested is that you download the VBA font encoder's .bas file and translate the Code128c function into TCL.

Note:
The IDAutomation Free Online Font Encoder Tool encodes Code 128 Auto, which does character switching. The data 00000 encodes as Set C for the first four zeros, then switches to Set B to encode the last zero. Therefore, the check digit and encoded data in the IDAutomation Free Online Font Encoder Tool may be different than encoding strictly in Set C:

The VBA's Code128c function is a direct demonstration of how IDAutomation products respectively calculate the encoding and check character.

I wanted you to walk through how the web page calculated the particular checksum.
