Potentially confusing code

I've decided to do this for future-proofing

%define da dd
%define resa resd

These should be used for any pointers to memory. Some of the old code still uses dd or resd though.

If we ever switch to 64-bit, then I'll change it to dq and resq, so that they have the appropiate size.
