Not particularly more efficient, but in my opinion more clear.

Replace:
D EntireBatch             DS            BASED( EntireBatch@ )
D                                       LIKE( OneRecord )
with:
D EntireBatch@    S               *

All you really need is the pointer.  Having the data structure could be
misleading to someone else looking at the program.

Since I always define all basing pointers explicitly, in my own code it
would be more obviously that the data structure is not needed.
