Hi
Thank you very much for the quick answer.
I think its about the 2 different compiler you can choose that confuse me.

I am running PBP 2.6.0B on a MacBookPro with Windows XP. My Mac is 64bit but i have no clue if Windows XP run 32 or 64bit.

At the moment i run the MPASM that was installed together with PROTEUS.

I am a newbie so what is your experience, is it better to choose the MPASM or the MP compiler?

Thanks Thronborg
