I pretty much figured out it was the AS/400 equivalent of a .tar That's part of the reason I'd like to hack it.

Maybe it's backwards compatible, with new releases having new features that are ignored by older versions, but that's fine with me--tar is like that. > > You're probably better off doing what other people suggest and just > restoring the SAVF to an AS/400, and then transferring the source out of > it directly.

Undoubtedly, but I don't like things like logic and practicality stop me when I'm on a roll ;-) > > On Mon, 31 Dec 2001, Jay 'Eraserhead' Felice wrote: > > > Just a question, anyone know of documentation of the IBM save file format? > > A pointer to ibm.com would be handy (I can't even seem to find their old > > AS/400 library either... they seem to have replaced it with this new-fangled > > thing with less information.
