[Zope] Newbie DTML: How do you just declair a veriable.

[Peter Sabaini]

not sure if i get you right. if you want to 

* include a string 'welcome' use
  
  <dtml-call "REQUEST.set('myvariable', 'welcome')">
  or
  <dtml-let myvariable="'welcome'">


* include the value of a variable named 'welcome' use

  <dtml-call "REQUEST.set('myvariable', welcome)">
  or 
  <dtml-let myvariable="welcome">

pretty much everything inside " quotes " is pythonic in DTML. you
might want to take a look at the DTML ref
(http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.html), esp.
the section "The expr attribute"
