This is a lot different than Masm, is there a file that explains this in detail ?

Does Linux use DOS-like interrupts ?

I think $0a is the Null character or newline ?

Thanks.

Code:

format ELF executable
entry _start

segment readable executable
_start:

        mov     eax,4
        mov     ebx,1
        mov     ecx,msg
        mov     edx,msg_size
        int     $80

        mov     eax,1
        xor     ebx,ebx
        int     $80


segment readable writeable
msg db 'First program for Linux using FreshIDE and FASM Thursday, March 21, 2013',$0a
    db 'Now Fresh can run Linux ELF executables. ', $0a
msg_size = $-msg

$0a is a line feed
$0d is a carriage return
null is usually 0
