[Zope] passing REQUEST.form to frames

What is the correct syntax for passing form data to child frames of a frameset ? I would like to pass form fields that is submitted to frameset to child frames. Is there any alternative built-in syntax to using an ugly construct like this : <!--#in "REQUEST.form.keys()"--><!--#var sequence-item url_quote -->=<!--#var "REQUEST.form[_['sequence-item']]" url_quote --><!--#unless sequence-end -->&<!--#/unless--><!--#/in--> ------------------ Hannu
