HTML: code "<":
==========================

 for(r=0;r&lt;rows;r++)

  {

   for(c=0;c&lt;cols;c++)

+It is not possible to use the less than (<) or greater than (>) signs in your text, because the browser will mix them with tags.

+To display a less than sign we must write: &lt; or &#60;



result: it works now !
