Good day, May I ask if there is a process where rexx code can be automated to update the change history in a natural program. Looking at REXX code to have a parameter which has the natural program name and where from REXX we can update the contents of a natural program directly eg. change history. Thanks. ---

This is possible, but not recommended. Someone (management, security department, …) might think you are trying to conceal code changes. Natural’s Application Programming Interface offers a couple of ways to modify source code. Take a look in the SYSEXT library. Also, the SCAN command might do the trick. ---
