Jim, what you want will probably be supported in the next release after
V4R5.  I say "probably" because nothing is certain until it's announced
yet.  You will probably be able to code something like this:

   D RNF_Data        DS                  Qualified
   D  NetType                       1A   Inz( *Loval )
    ...
   D  NetNumber                    10U 0 Inz( 0 )
   D                               95A   Inz( *LoVal )

   D Data            DS                  LikeDS(RNF_Data)

Currently, all you can do is create a physical file with the layout you
want, and use externally-described data structures.
