What do you mean by "all of it's contents"?  Do you just mean a list of
files similar to what the DSPSAVF command gives you, or do you want the
actual data in the objects?

Why do you want it in a physical file?  Are you going to run queries over
it?

If you just need the data in an RPG program, run the API when you need it.
No reason to store it in a PF -- then you have to keep the PF in sync with
the SAVF.

Depends on what you need, I guess.  I know that Leif has written quite a
bit about savf internals in his MI programming e-book.  More info about
that is on his web site:  http://iseries.org

If you want to read the raw data that's inside a savf, you don't even need
APIs.  Just declare an F-spec for a flat file with (IIRC) a 512 byte
record length and override it to the SAVF before reading...

There have been some discussions about the internals of save files in the
MI400 mailing list as well.  IF that interests
you, go to http://archive.midrange.com and search the MI400 mailing list.
