Yes, I'm talking about an AS/400 PF, or save file.   I have no idea what
oracle or access files look like on the AS/400.   I assume that they're
normal stream files :)

Well, if we could determine that it's a native object of type '*FILE',
and we could determine the final library/file name, then we could 
retrieve the object attributes to find out that it's a save file.

Not sure that I'd want to decide that it's a save file just because it's
a PF with a 528-byte record :)

A symlink just redirects which file gets opened from one location to
another.   So if you do a open('/test/somelink')  and somelink is a
symbolic link to '/QSYS.LIB/DATALIB.LIB/CUSTFILE.FILE' you'd actually
be opening DATALIB/CUSTFILE in your attempt to open /test/somelink.

Does that make sense?  If not, I'm not sure how to explain it... :)
