Why doesn't anything work in assembler? Is sasm stuck dead?

Question

assembler

Need to write a program that would add 1 + 2? Why does not a single example from already 10 sites work for me, I downloaded 3 sasm esm fasm compilers and besides the fact that in each example the syntax is completely different, none of them worked.
For example, sasm generally freezes completely,
And why are there 3 different forms of include
@include "dfdf"
include `dsds`
include dekde

Answer 1

Keep under x86

mov eax, 1
add eax, 2
