OK, now a problem with both of these is that they require a closing
tag.  What I need to do is set a variable only if it is not already
passed in.  Ie:

<dtml-unless myvar1>
  Set myvar1 here
</dtml-unless>
  
 various code here that uses myvar1

But, dtml-with or dtml-let won't work, because I have to close the
tags for them before the closing dtml-unless tag -- I can never get to 
the code below with the new value.  How does one get around this?

Thanks,
John
