title: Input in Assembly Language
body: <p>I've got some problems with Assembly Language.
  The user have to enter some number from keyboard and then i'm going to do some operations with that number.
  Is it ok to use this:</p>
  
  <pre><code>LEA DX ,SIZE;before in SEGMENT "DATA": SIZE DB 7
  MOV AH,9
  INT 21H 
  </code></pre>

  Thanks.
  P.S.
