Data Structure with same physical file format and fields two times

All,

I know it must be something simple that I am missing. I want the structure
of a physical file in my program twice, renaming the fields so I can compare
a before and after picture.

My code;

* Old record data structure
D oorddtl E DS EXTNAME(myfile) prefix('or':2)
D
* New record data structure
D norddtl E DS EXTNAME(myfile) prefix('nr':2)
D

The compile error I am getting is;

*RNF3534 20 a 003500 The parameter for keyword PREFIX is not valid;
keyword is ignored.

As I am still new(er) to ILE RPG (reformed COBOL programmer and previous RPG
III programmer), my reading of the manual says this should be possible. So
what am I missing?

Thanks!

JIm
