title: Escape single and double quote in TCL
body: <p>I am using the following script , but it is throwing error message<br>
  tcl;  </p>
  
  <pre><code>eval {
       add command "Audit Param"\
       setting "Error : Part's and Spec's desc contains \"OBS\" or \"REPLACE\"" "(Reference No)"\
       user all;
  }  
  </code></pre>
  
  <p>It is showing error as : <code>Expected word got 'and'</code>.<br>
  I tried with <code>Part\'s</code>, but still not working. How to escape both single and double quote , if it is having both?  </p>
