[Zope] Is it possible to call make odbc calls from an external method?

hi, I just created an external method that... def test(self): import sys return sys.modules ...and then a DTML method that... <dtml-in "test().keys()"> <b><dtml-var sequence-item></b><br> <dtml-let x=sequence-item> <dtml-var expr="dir(x)"> </dtml-let> <br><br> </dtml-in> ...because I was try to get zope to describe itself. What I want to do is use the odbc stuff from within an external method. Is this possible? And why doesn't dir(x) in the DTML above work? thanks tom
