Melanie, Thanks for the prompt response. I first went to microchip and on their home page typed MPASM into their search bar. It took me to a page where I downloaded what appeared to me to be the latest versions of MPASM. MPASM™ Assembler Last Updated: 7/21/03

Following your advice, I have now tried again to find MPASM but this time went into the QuickLinks search bar and clicked on the development software area where I can find MPLAB IDE ver 7.20 and 7.22 but no direct reference to MPASM. I am downloading this monster now, but it will take a while.

I did try commenting out the @_config_ line earlier but no joy. You are probably right in suggesting a version issue. The MPASM I am downloading is version 5.00 which is included in MPLAB 7.22. Does this look like the right version?

Cheers
Brian
