title: Whats the difference between .asciiz vs .ascii
body: <p>I read that .asciiz null terminates the string (appending <code>\n</code>?) ... but when looking at the User Data Segment of QtSPIM, </p>
  
  <pre><code>User data segment [10000000]..[10040000]
  [10000000]..[1000ffff]  00000000
  [10010000]    6c6c6548  6f57206f  00646c72  6c6c6548    H e l l o   W o r l d . H e l l 
  [10010010]    6f57206f  00646c72  00000000  00000000    o   W o r l d . . . . . . . . . 
  [10010020]..[1003ffff]  00000000
  </code></pre>
  
  <p>I don't see a difference? </p>
  
  <pre><code>.data
    str1: .asciiz "Hello World" # string str1 = "Hello World"
    str2: .ascii "Hello World" # string str2 = "Hello World"
  
  .text
    .globl main
      main: 
        li $v0, 4 # print_string
  
        # print(str1)
        la $a0, str1 # load address of str1 into $a0
        syscall
  
        # print(str2)
        la $a0, str2 # load address of str2 into $a0
        syscall
  
        j $ra
  </code></pre>
  
  <p>Outputs "<em>Hello WorldHello World</em>"</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>What are the implications or when do I use each? <code>asciiz</code> sounds like the "proper" method?</p>
