[Zope] How do you increment a variable?

[Tony McDonald]

This works. Looks damn ugly though...note that there's no <dtml-let> 
tags evident (I believe <dtml-let> creates *another* namespace, apart 
from the REQUEST one). I could really do with help on my other post 
though on 'Interrogating DTML...'

<dtml-call "REQUEST.set('counter', 1)">
Counter:<dtml-var counter>,
<dtml-call "REQUEST.set('counter', counter+1)">
<dtml-var counter>
