If I compile this, I get value out of range for both al assignments.
I have version 1.71.01 here.

Oh yeah, so it does. I didn't see the new version there, I was using 1.71.24.

Well, this one has nothing to do with define/equ.

Well, simple " use32 | mov eax,[$FFFF'FFFF'FFFF'FFFF] " "works" in 1.71.25 ... no need for "define" or "equ".

Define or equ should work anyway.
If there is a simple bug this should be solved in the next version.
