Re: Data Structure with same physical file format and fields two times

Why not simply use a qualified name?

d orddtl e ds ExtName(myfile)
d Qualified
d nordtl e ds ExtName(myFile)
d Qualified

If Orddtl.Field1 <> Norddtl.Field1;

or just

If Orddtl <> Norddtl;

Upper case prefix maybe?

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!
