Hello World in WinAsm please

Gentelmens ,
I want to ask you to wirte a correct hello world programm in winasm ide.
I do thank you in advance.

P:s: i have tried following but there were errors at executing it.

section .text
global _start ;must be declared for linker (ld)
_start: ;tells linker entry point
mov edx,len ;message length
mov ecx,msg ;message to write
mov ebx,1 ;file descriptor (stdout)
mov eax,4 ;system call number (sys_write)
int 0x80 ;call kernel

mov eax,1 ;system call number (sys_exit)
int 0x80 ;call kernel

section .data
msg db 'Hello, world!', 0xa ;our dear string
len equ $ - msg ;length of our dear string

Hi Vad,

I'm not sure if you have pasted the correct source code into here, since -to me- it looks like it uses linux syscalls... since board name is winasm, not linasm, i suggest you to search some more for examples.

Regards.

P.s.: heres my example hello world:

.486
.model flat, stdcall
option casemap:none

include windows.inc
include kernel32.inc
includelib kernel32.lib
include user32.inc
includelib user32.lib

.data
cCaption db "Caption",0
cText db "Hello World",0
retval dd ?

.code
start:
invoke MessageBox, NULL, addr cText, addr cCaption, MB_OK
mov retval, eax
invoke ExitProcess, 0
end start

---
edit: last invoke of exitprocess used wrong return value, thanks for pointing this bug out to ragdog!

??

invoke ExitProcess, 0

greets,
