title: NASM printing out time - code doesn't output anything
body: <p>I'm just getting started with ASM (NASM), and need some help with the following snippet.  I get no errors/warnings, it just doesn't output anything.  What I was expecting was for it to get the time (13), then print that out (4), then exit (1).  Also, does anyone know of some good (preferably NASM specific) ASM tutorials?</p>
  
  <pre><code>section .bss
    time:   resb   255
  
  section .text
    global _start
  
  _start:
    mov   eax, 13
    int   0x80
    mov   eax, time
  
    mov   edx, 255
    mov   ecx, time
    mov   ebx, 1
    mov   eax, 4
    int   0x80
  
    mov   eax, 1
    int   0x80
  </code></pre>
