title: Ada fill constant string with Nulls
body: <p>I want to make a constant string that looks like:</p>
  
  <pre><code>My_Null_String : constant String(1 .. 50) := "NULL***********************";
  </code></pre>
  
  <p>with all of the *s being <code>Ascii.Nul</code> characters.  It is not possible to do this via the <code>others</code> keyword, as in:</p>
  
  <pre><code>My_Null_String : constant String(1 .. 50) := "NULL" &amp; (others =&gt; Ascii.Nul);
  </code></pre>
  
  <p>Is there an elegant solution to this that doesn't involve a huge block of <code>Ascii.Nul</code> characters to fill out the rest of my string?</p>
  
  <p>Thanks</p>
