I have got such good help in the past from every one here I figure I should try it again. My problem is my ACL (ascii clear buffer). I am reading a 42 character bare code into channel 0. My data and string conversions are great. The problem I am having is that my control DN bit is what is currently clearing my buffer. However some times after a block has left the cooler before it makes it to the barcode scanner the label gets smugged or smeared. when this happens then the scanner will only pick up a limited number of characters, this is good because this block would be rejected. the problem is that the next block is also rejected because the first partial scan characters are still in the buffer which are then compiled with the characters from the second block. This changes the ascii file in the buffer so that it no longer within the parameters. In short I need a way to clear the buffer when the scan isn't complete. It seams like hing I use ends up giving me an error in my ARD instruction.
