CCI.INI may be located in a number of locations for testing and deployment. The Windows root directory is a good location as it is visible from all applications, on Windows systems of all types. The COBOL cobdir/bin installation directory or the application's current directory are good logical locations on UNIX systems. There may be configuration sections for more than one CCI protocol module in any CCI.INI file so care is required when choosing the location for a CCI.INI file. If you only want to affect the behavior of a single application, rather than affecting every application on the system, put the CCI.INI file in the current directory, from where the application is being run.
