title: How to put block comments in Tcl?
body: <p>I have code here</p>
  <pre><code>proc checkPrime {no} { 
      set i 1 
      set count 0 
      while {$i &lt; $no} { 
          if {{$no%$i} eq 0} {
              incr count 
          } 
          if {$count eq 2} { 
              puts &quot;the number is prime number&quot; 
              return 
          }
          incr i 
      } 
  } 
  </code></pre>
  <p>I want to put the whole procedure into a single comment, I don't want to have to put <code>#</code> before <em>each</em> line.</p>
  <p>Is there any possibility to comment multiple lines in Tcl, as there is in Java using <code>/* .. */</code>?</p>
  <p>I also want some of the text will be put into a single comment</p>
