Problem:

Is it possible to get runtime configuration file name from within a cobol program?

Resolution:

There's no library that does this automatically.

The easiest way is to declare an environment variable in the same config file that indicates the name of the file, such as:

CONFIG_FILE_NAME C:\\etc\\cblconfi

Then you can accept this variable form cobol with the statement:

ACCEPT dest-item FROM {CONFIGURATION}

                       {ENVIRONMENT  }

                      "CONFIG_FILE_NAME"
