      To: dev@velocity.apache.org

      Hello,In the Evaluate section, there are two different variables: $source1
      and $source. How can it display "abc" when $source is never defined?

      Evaluate

      The #evaluate directive can be used to dynamically evaluate VTL. This
      allows the template to evaluate a string that is created at render time.
      Such a string might be used to internationalize the template or to include
      parts of a template from a database.

      The example below will display abc.

      #set($source1 = "abc")
      #set($select = "1")
      #set($dynamicsource = "$source$select")
      #evaluate($dynamicsource)

      That's a good point though. Perhaps the example should use concatenation to be clearer. The single quotes prevent evaluation.

      #set($dynamicsource = '$source' + "$select")
