[Zope] Passing variables to a DTML method ...

Could someone explain how to pass variables to a DTML method? For example, if I have the following in a DTML method: <dtml-call "REQUEST.set('testvar', 'value')"> <dtml-var "calledmethod(REQUEST)"> How can calledmethod access the variable testvar? I thought that calledmethod gets the REQUEST namespace on thus <dtml-var testvar> would work. I read Amos' How-to: http://www.zope.org/Documentation/How-To/AdvancedDTML but I'm still struggling.
