I don't mean to be critical, but this is a good example of a bad post. I explicitly stated that I had read the man page for this module and that it had not helped. Restating it does about as much good as speaking loudly and slowly to foreigners.
The 'else' that is needed is in the posts below this. For example, the man page makes no reference to the ability to select AnyDBM_File as a DB type.
Thanks to everyone else who posted too, btw, I got just what I needed.
