I am looking at some very old (Nat 6) code that I wrote over 30 years ago for a DOS/VSE mainframe. It has since been ported down to Windows. Of course over 30 years it has changed. I am trying to figure out some way to map source code in the production library to DDM’s - mapping on the table level would be great, field level even better. Any suggestions about either a Windows solution (exporting to text, etc) or a natural utility that might be available - remember it is Nat 6. And it is still running. Kudos to SAG, Thanks in advance. ---

The simple answer is to use the cross-reference feature of the Predict data dictionary via the List Xref command, abbreviated L X. If Predict is not installed, you’ll see a NAT4488 message. If you don’t see cross-references, you’ll need to turn on the feature (“xref on” command) and then CATALL to generate the data in the Predict repository. Natural Engineer would do the trick, too. ---

Predict is not installed. The customer is not current on maintenance or upgrades - they have a stable environment running their core business. It’s unique because they truly could just keep running until something changes that cause the collapse of a product which is wholly unsupported. My job is to try to get them off the platform while preserving the functionality defined thirty years ago. ANd modified a lot of course in the subsequent time period. Without predict, I was hoping there might be a DBA utility or user function which might be able to help. I think I will have to export all the source code out to text and do my XREF outside the natural environment. Thanks for the answer though. ---
