### Using Natural Objects Created in Previous Natural Versions

Natural objects that were created with Natural for Mainframes Version 2.3, 3.1, 4.1, 4.2, 8.2 or 9.1 can be executed with Natural Version 9.2 without any adjustments to the objects or any conversion or migration procedure being required. This also applies to objects that have been cataloged with the Natural Optimizer Compiler.

Important
Objects cataloged with a Natural Version prior to 2.3 must be recataloged before execution with Version 9.2. This also applies to data areas that are used by these objects.

It is strongly recommended that any existing objects be recataloged with Natural Version 9.2 to take advantage of improved runtime handling.

### Special-Purpose Zaps

The following table lists Natural Version 9.2 Zaps and the special purposes they support:

Zap | Special Purpose
--- | ---
NA21002 | Suppress NAT3145 error information | Suppress extra L2 calls to Adabas after a NAT3145 error has occurred. If this Zap is applied, the application programming interface USR8202N no longer provides extended information on the NAT3145 error message.
NA21003 | Resolve problems (RSP=46) during Natural for z/OS calls to Adabas for Windows, Linux and Cloud | Resolve problems that can arise when Natural calls Adabas on Linux, UNIX or Windows from a z/OS platform: an unexpected RSP=46 can occur if a READ loop at the level 1 (*LEVEL=1) ends with an End-of-File (RSP=3) and is executed multiple times. This occurs because Natural on z/OS does not send a final RC command to release the Adabas Format Buffer if the READ receives RSP=3.

Note
Former special purpose zaps are either replaced by parameters (e.g. Support for the Arabic shaped format) or will no longer be required for Natural version 9.2.4.
