Retrieveing contents of message file

Fellow experts...

I'm working on a little message utility (which will end up being open source
of course)

What I am trying to do is list the contents of a message file.  Not
necessarily the descriptions, but just the message Id's.
I notice when doing a DMPOBJ that a message file is an index.  But how can I
access this either from RPG or C (maybe even MI).
I would prefer this to work on any 400.

I could use the standard API's, they cater for positioning, so long as you
know where to position to (in the case of a roll back, you don't know where
to start from)

Any help greatly appreciated!
