Heh :) I was afraid you guys might say something along the lines of "Pay
up first, you cheapskate". Nice to see otherwise.

I'll be writing product code, and am currently just experimenting via
zopectl debug, so I have full access to everything.  But I still can't
see how to get a cursor or anything else that will let me retrieve
multiple record sets from one STP call.

What should I be looking for?

./bin/zopectl debug
Starting debugger (the name "app" is bound to the top-level Zope object)

I guess I could just use mx.ODBC instead of mxODBCZopeDA, but then I'd
lose the nice Zope DA features like transaction integration and DTML
support ...
