title: Updating value at address stored in register in MIPS
body: <p>I have an character array initialized under <code>.data</code> as follows:</p>
  
  <pre><code>array: .byte '-':42
  </code></pre>
  
  <p>Say I load the address of the array into <code>$t0</code>:</p>
  
  <pre><code>la $t0, array
  </code></pre>
  
  <p>I want to change the character stored at the address in <code>$t0</code> to the character 'X', but I'm having trouble accomplishing this.</p>
  
  <p>Thank you!</p>
