Datafile as child of listing?

[Andrew Scholer]

Would it make sense to allow a datafile as a child of listing?

I want to xref some datafiles, the natural way to allow that would seem to be putting them into a listing. But currently only programs and consoles are allowed.

Sounds plausible. I can't recall exactly how these render, so I'd like to have a look before giving a final answer. In a few days. -Rob
