Run-time System Configuration

Restriction: The run-time switches and run-time tunables are supported for native COBOL only.

You can configure the COBOL run-time system environment to ensure it behaves appropriately for an application, regardless of the configuration used by other COBOL applications.

Run-time behavior can be controlled using environment variables, a run-time launch configuration file, run-time tunables, and run-time switches.

You can specify some run-time features from within the IDE, as well as in a separate configuration file:

  • From the IDE - Setting certain run-time features in the IDE generates a binary format file. In Visual Studio you can add an Application Configuration File item (a .config file) to a project.
  • A separate configuration file - In a text editor, create or edit a separate text file. See the individual sections for the formats of the text files. Use the COBCONFIG_ environment variable to specify the location and name of the run-time configuration file for environment variables, tunables, and switches.
