And DSPDBR gives you a list of the files that are dependent on a file, so
you could run that against each file in the main library. To an outfile.

I had thought you would need to run it against logicals, if they are
SQLtype VIEW, since views can be built over views, not just tables. But it
turns out that views over views get listed under the final base physical.

BTW, views can be created over views but not over normal logical files.
