title: Array length (columns and rows)
body: <p>Alright, so I script some game in Assembly and trying to get the array length of a defined DB. I use TASM. I know there's this command to find an array length <code>len equ $-a</code> but it's not what I specifically need.
  For example, my a array looks like this:</p>
  
  <pre><code>a DB '0','2','0','2','0','2','0','2'
        DB '2','0','2','0','2','0','2','0'
        DB '0','2','0','2','0','2','0','2'
        DB '1','0','1','0','1','0','1','0'
        DB '0','1','0','1','0','1','0','1'
        DB '3','0','3','0','3','0','3','0'
        DB '0','3','0','3','0','3','0','3'
        DB '3','0','3','0','3','0','3','0'
  len equ $-a
  </code></pre>
  
  <p>Now, if I use the array command I specified above, it will return 64. What I need is for it to return 8 like the line's number of values.</p>
  
  <pre><code>DB '3','0','3','0','3','0','3','0' = 8 values
  </code></pre>
  
  <p>Is that even possible? Thank you!</p>
