Parameters for Zope External Method

[Jyrki Alakuijala]

I have succeeded in creating a Zope external method which
causes a python statement to be evaluated for a web request.
However, I have failed to pass parameters (other than the
special case "self") to that external method.

So, where can I find instructions on how to call an external
method with parameters? I could not find that in the
manuals.

Should I use something else than an external method?
