Some hints to play with (tested on 2.3.0):

<dtml-if "REQUEST.form">
  <dtml-var "REQUEST.form"><br>
  <dtml-var "REQUEST.form.keys()"><br>
  <dtml-var "REQUEST.form.values()"><br>
  <dtml-var "REQUEST.form.items()"><br>
  <dtml-in "REQUEST.form.items()">
    <br><dtml-var sequence-index>: <dtml-var sequence-key>=<dtml-var sequence-item>
  </dtml-in>
<dtml-else>
  No parameters given!
</dtml-if>
