title: Combining values of two registers into a single variable
body: <p>I am using tasm. The question is kind of basic but I can't remember how to do it. Apologies for that, My question is that suppose I have two registers with different values and I wish to combine (merge) them  and save the value into a single variable. How would i do that?
  Suppose <code>ah=01</code> &amp; <code>al=04</code> . I wish to merge them into a single value of <code>14</code>, hex equivalent <code>0E</code>. Any ideas?</p>
