x86 assembler in 512 bytes of x86 machine code

0asm's Issues

Technical questions

Hi Keyhan!

I'm very impressed with this project!
I've developed my own tiny OS inspired by bootos.
The only 'development environment' it supports is a hex editor that allows to input machine codes directly into memory.
I then run those commands via a far jump.
Now the problem is that hand assembling is quite painful and I was looking for a way to come up with a tiny assembler,
but since the size of apps for my OS is limited to 512 bytes it seemed impossible to find an assembler of that size but then
I eventually found your project. Could you please kindly answer a couple of tech questions?

1. Do I understand correctly that asm source file is loaded from floppy image?
2. If so - what's the address for that and can I point SI there to make assembler processing what I've typed from keyboard?
3. And instead of writing machine codes back to floppy I'd like to write to memory (for later execution)

Is it possible?
If so and if I'm smart enough can I use 0asm in my OS project? (it's not commercial obviously and I'm running it for youtube video purposes)

THANKS IN ADVANCE!
