Where to write in Assembler?

Question

assembler

I want to learn assembler, but I don't know where or in what program to write it. I want to study it in order to make my own operating system in the future. Tell me which assembler is suitable: NASM, FASM, ASM, etc.

And one more thing: where to learn it and in what program to write?

Answer 1

Unfortunately, your question is similar to "which assembler command pacman eats the devil".
You are asking this question too soon. Before you learn assembler in order to make an Operating System, you should study how an operating system works in general, how programming languages ​​work in general. That is, to begin with, become an advanced user.
First, learn C/C++ to a level so that you can write simple console programs like "open a file, write something to it", "open a file, read something from it".
Then you can study how the operating system is loaded from disk, figure out what the BIOS really is (and not think that bios is a menu in which you can choose to boot from a disk or flash drive), and think about whether you can write your own operating system bootloader .
Then you can read / look through at least 1-2 ANY books on assembler (and don't be afraid to ask such simple questions to Google). It makes no sense to recommend the best to you.
And questions should be asked when you already know about half the answer. Then those are the right questions.
