Ugliest ASM source code ever?! (Developers)

Can you top this?

JMPS(S) =A1= 'Hello World !' =A2= 0A =S= AX,B800;ES,AX;AX,3;INT10 CX,(A2-A1);SI,(A1);DI,500 AH,[(A2)] =L= LODSB;STOSW;LOOP(L) RET

This was a short example from http://www.evmsoft.net/ru/asm.html.
Another one (from the archive):

ah,09;dx,(str);int21;ret =str= 'Hello USSR !!!$'

Now imagine the whole assembler (>32k) is written in this style! The problem is not the syntax itself, although it's different from any other x86 assemblers. But why would anyone format his/her source code like that?

BTW I don't like AT&T ASM but this seems to be even worse...

Well-formatted:
=start= ah, 09 dx, (Message) int 21 ret =Message= 'hello, world'; 0D; 0A; '$'

An x86 assembler in 7,777 bytes is not bad.

True, although I've not tested that one (yet?).

But that reminds me of the one by Venkat Iyer (actually smaller, barely, ~7200 bytes):

* https://github.com/catb0t/x86-s
* https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/devel/asm/venksi/

IIRC, the LF ending fix (not in a full, newer release) was requested by Fabrice Bellard for his JSLinux since he included it there (for obscure reasons). I'm sure Arjay can tell us more. :-D

I don't have tons of experience with it, only wrote (ported?) like two extremely simple utils to it, for fun. It, too, is a bit quirky in syntax, but it does work! (It can also assemble itself, so that's good.)
