Well, i was not clear.

In 
<dtml-unless SOMEREQ>
 <dtml-call "REQUEST.set('SOMEREQ','defaultvalue')">
</dtml-unless>
the problem is SOMEREQ is *hard* coded in the DTML document.

I need to have EXACTLY the same behaviour (checking if 
SOMEREQ is in the REQUEST, and set it.

If i use a property (PropName) for putting the name of what i want 
to check (SOMEREQ in my case), only the REQUEST.set works.

the <dtml-unless is checking for PropName in the REQUESt and 
NOT *value* of PropName

So in your example, SOMEREQ is *still* hard coded. From what i 
understood.

Sorry, but as you already guess it, Zope is not my native language 
and English either ;-<
So thanks for trying to understand MY english ;->
