Thanks Mike, that's good advice but... I'm not an ASM or XC8 person which is why I use PBP and just made the upgrade purchase online (thanks Henrik).

My knowledge of C is very limited but if I have to I'll have a go, assuming PBP doesn't come to the party soon enough, but that then begs the question: what's the use of PBP if it is relegated to dinosaur chips?

Kind regards,
Bill
