For completeness one should mention that this example is x86 assembler (not even amd64!), and for extra credit how about ARMv7, SPARC and POWER versions too? :p

Yes, thought it would be better to start with the basics.
global _start
section .text
_start:
mov rdi,1
mov rsi,hello_world
mov rdx,hello_world_size
mov rax,1
syscall
mov rdi,0
mov rax,60
syscall
hello_world: db "Hello, world!",10
hello_world_size EQU $ - hello_world
How about one for Windows 64?
extrn ExitProcess: PROC
extrn MessageBoxA: PROC
.data
caption db 'Windows 64-bit hello!', 0
message db 'Hello, world!', 0
.code
Start PROC
sub rsp,28h
mov rcx, 0
lea rdx, message
lea r8, caption
mov r9d, 0
call MessageBoxA
mov ecx, eax
call ExitProcess
Start ENDP
End
