If you want a variable whose scope is a single request, then use the REQUEST
object. If, on the other hand, your purpose is to work around the fact that
DTML is not a general purpose language, but rather a document templating
language, use PythonScripts instead. IMHO, of course.

There's at least two ways to pass variables between DTML-objects:

<dtml-let var1="'one'" var2="'two'">
<dtml-var other_dtml>
<dtml-var "other_dtml(_.None,_,var1='three',var2='four')">
