Hi Tony, generally the special ID locations cannot be
read by the PIC itself. I prefer to put the ID in
the ROM as part of a general data table showing DOM,
batch number, firmware version etc. This can then
be read by the PIC itself and displayed when operating.

The ideal way to store the number in ROM is as one
or more RETLW bytes, for obviosu reasons. :o)

Having it open source is a good idea! I could modify
the souce and do it that way, just thought that you
may have other customers that want to number their
products.:o)
