Fool's errand? I would say that depends. If you're willing to think in
terms of "information flow" rather than *parameters* per se, then it's
fine.

The simplest and most straightforward way to get information out of
called Python code is for the Python code to "leave" it somewhere to
be picked up by the caller. (I use this verbiage to contrast with the
idea of "passing" information directly back to the caller.) The most
natural choice, from the Python side, would be an IFS stream file. But
it should be fairly easy to leave the information in a database table
or other QSYS.LIB objects (via iToolKit).

Thanks John. I'm good with the idea of information flow. The
irritating part is that the Python is essentially a perfectly
self-contained unit of work. I just need to plumb it in for a finished
application and I worry that the plumbing will be ugly. Maybe I should
stop worrying and keep writing code :-)
