Run-time System Configuration

When applications run, they use a run-time system: the shared run-time system.

You can control the run-time behavior by creating a run-time configuration for the application. This configuration ensures that the COBOL run-time environment always behaves appropriately for the application, regardless of the configuration used by other COBOL applications.

You can configure run-time behavior through environment variables, run-time tunables, and run-time switches.
