# Environment Variable

Set the `CORTRACE` environment variable to the required trace level. See your operating system documentation for further details.

Note
The `TRACE` setting in the Initialisation File takes precedence over the `CORTRACE` environment variable. The `CORTRACE` environment variable will only be used if the Initialisation File cannot be read or the `TRACE` setting in the initialisation file is missing, invalid or set to zero. This means that the `CORTRACE` environment variable has no effect if there is a valid non-zero `TRACE` setting in the initialisation file.
