[Zope] Calling ZSQL methods with implicit arguments

Hi, Usign the dtml-in tag I can iterate over the results of a ZSQL method without explicitly passing the arguments, e.g: <dtml-in myZsqlMethod> ... </dtml-in> Now, what I want to do, is not to iterate but simply to store the Results object in a variable (in DTML or even in an External Method, I don't care), so I can later pass it as an argument to another method. However simple this looks, it seems that when I use the ZSQL method inside an expression I must use Explicit arguments, meaning I can't do something like <dtml-let results="myZsqlMethod"> ... </dtml-let> Is this possible? Am I missing somthing terribly obvious? Thanks in advance, Nuno
