Viv,

My head is still swimming with this Code 128 project.

I tried prepending the Chr(104) to the string prior to sending it as you suggested, but I am still getting the weird character on the front of my label.

I am using a different checksum calculation program exmple I found at:

I used this example, but still no workie.

Do you know the significance of the Chr(162) and Chr(164) in his final line of code?

OUTSTRING = CHR(162) + MYSTRING + CHKCHR + CHR(164)
