title: MARS MIPS assembler gives error: Extended (pseudo) instruction or format not permitted
body: <p>In Mars (an IDE for MIPS) I found really strange errors.  The sample code is like this</p>
  <pre class="lang-assembly prettyprint-override"><code>.text
  .globl main
    main : 
    la $a0, msg
    li $v0, 4
    syscall
  .data
    msg: .asciiz &quot;Hello World&quot;
  </code></pre>
  <p>and the error message is:</p>
  <blockquote>
  <p>Extended (pseudo) instruction or format not permitted. See the Settings.</p>
  </blockquote>
