Hello World assembly language

[Nate Dobbs]

Alter the stuff in red, the message will print irrespective of your
`message' length.

Change 13 to 14.



section .data

message:
db      'hello, world!', 0x0a

message_len equ $-message


section .text

global _start
_start:
mov     rax, 4
mov     rdi, 1
mov     rsi, message
mov     rdx, *message_len*
syscall

mov     rax, 1
xor     rdi, rdi
syscall
