Hi Benoit, AFAIK, the _ is used as a hack. _ actually is the namespace variable, but in this case: REQUEST['var'] and _[REQUEST['var']] is no different. You use the _['something'] construction when a dash is used in the name: <dtml-var sequence-item> works by itself. If you want an expression of that: <dtml-var "sequence-item-5"> does not work because it syubtracts item from sequence and five from item. Instead use: <dtml-var "_['sequence-item']-5"> It is a hack where _['a-b'] forces a-b transalated by zope as a_b so there is not expression problem. Did I miss anything, oh great zopemasters?
