I will add it to the documentation. This is important for users with newer machines.
I would love to add signed ints and even maybe floats. It's just out of my scope at the moment. I need more time to study it all. And assistance. The FASM community has been very helpful and friendly so far, so we will see where the future takes this.
One way to look at my compiler is that it has a lot of information on asm programming packed into one place. It's io.lib and include libraries have a ton use useful routines that an asm beginner could make use from. It also supports inline asm which makes it like a vessel to program in FASM with.
