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

You need to specify it without the single quotes.

I will suggest though you don't use the prefix keyword and instead use
qualified data structures.

* Old record data structure
D oldDetail E DS EXTNAME(myfile) qualified
D
* New record data structure
D newDetail E DS EXTNAME(myfile) qualified
D
...
/free
if (oldDetail.field <> newDetail.field);
// do something
endif;

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
