Thanks Darrel, sorry for the trouble. I must have had a weird MPLAB/MPASM install issue at work. Mpasm showed the include file, but MPLAB 8.33 I couldn't see the chip in the drop down box. Definitely missing something. Anyway, it worked fine at home, but it didn't like my slightly altered .inc files. I had to delete a few to make the update install.

Thanks again.
