Re: HP 41 Bar Code Language Message #5 Posted by Ray on 5 May 2004, 1:39 a.m., in response to message #1 by Cristiano
The barcode also uses two bars of data on each side to indicate whether data is being read left to right, or right to left. I think it works like this in a string of data:
00DDDDDDDDDDDDDDDDDDDDDDDDD10
Where:
D=data string itself (could be anything)
0=thin bar
1=thick bar
This shows how the ends of the data are organized, so the reader knows whether it is reading right to left or left to right.
Someone correct me if I'm wrong. Hope this helps.
