Hi Darrell--

Thank you for taking a look at this! That was, in fact, the problem. I turned off the serial number programming feature and it worked, and I verified that by turning the serial number feature back on, and adding a DEFINE RESET_ORG xx instruction at the top of the code, and it worked as well.

So what is it about the LCD command's presence that makes the code work? Does LCDOUT force a different start for the code?

Thanks--
