One of the many way to execute an operator command from a batch rexx program.

With this solution here, with Rexx and SDSF, you can embed the commands in more complex business logic, and use Rexx variables to dynamically establish values for the commands to be issued.

By the way I have started a repository on GitHub on which I will share assets in the future.

I have added this tool here:
