These sound like questions that Natural Engineer can answer. It is also possible to get some helpful information with Predict XREF to identify objects that exist but are not referenced.

I don’t think one can provide “code” to answer your questions.

Brian is right.

Here’s a screenshot of the regarding Predict XREF menu:

```auto
 10:32:07 *****P R E D I C T 4.6.1***** 2011-05-13
 Library: TEST - Verify Appl. Integrity - DBnr: 22 Fnr: 20

                 Code Function

                   X Consistency of application
                   I Objects not implemented but referenced
                   R Objects implemented but not referenced
                   A Verify all

             Code: ?

Command ===>
Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12---
      Invp GDAV Quit Sets Rule Copy Xref View OSet SPfk Main Exit
```

And the submenu “Objects implemented but not referenced” looks like that:

```auto
 10:32:40 *****P R E D I C T 4.6.1***** 2011-05-13
 Library: TEST - Verify References - DBnr: 22 Fnr: 20

                    Code Function

                      D Data areas not referenced
                      V Variables in data area not referenced
                      U Programs with unused data areas
                      C Copycodes not referenced
                      N Error numbers not referenced
                      P Programs not referenced
                      I Programs not impl./ref. starting from one

                Code: ? Save set: N (Y,N)
           Data area: Data area type : (?)
        Program type: (?)
             Program:

Command ==>
Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12---
      Invp GDAV Quit Sets Rule Copy Xref View OSet SPfk Main Exit
```

My guess, and that is all it is, a guess, is that you are somewhat new to Natural. As the “newbie” you have been given the task of “cleaning up” some old code. Before you go down the wrong path, you might want to consider:

1. Variables in a data area not used in a main program.

2. Unused subroutines

3. references to objects that are not executed

As Brian indicated, the only software that really exists are add on products, whether from Software AG or other vendors. Depending on the size (number of objects, size of the objects) of the system, you may want to employ a lot of your own “elbow grease” and use SCANs to find references. This is an excellent way to learn about a system.
