The easiest way is to use REQUEST.set:
<dtml-call "REQUEST.set('myvariable','myvalue')">

Another way to do it is to use dtml-let. This is "cleaner" if you will
only need the variable for a short time.
<dtml-let nums="(4,5,6)">
  nums forward:
  <dtml-in nums><dtml-var sequence-item> </dtml-in>
  nums backward:
  <dtml-in nums reverse><dtml-var sequence-item> </dtml-in>
</dtml-let>

Nums only exists between the two <dtml-let statements>.
