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

[James Perkins <jrperkinsjr@xxxxxxxxx>]

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;
