Uttam is making the simpler type of assembler. In my opinion writing linkers is hard work. Writing an assembler (even a relocatable one) is fairly simple.

I would agree that separate object modules are a lot easier in a larger project. I have seen some fairly large assembler projects that are written in modules but assemble in one go.

When free tools exist, I admire someone for jumping in at the deep end. Uttam's time could be better spent on his real project. But that is his choice.

I am sure that "absolute" addressing is not a British expression. I have used the term in symbol tables and expression evaluators, and relocating linkers.
