The site customization file (G1CPFDF) is an updateable indexed file for the interactive system. If you plan on modifying default initialization and processing values for your site, you need to install the customization file. Otherwise, the interactive system will function with the default match settings and processing on entry to and exit from the CODE-1 Plus software.
Note: The customization file is required for accessing the Geographic Coding Interface screen. If the customization file is not available, the Geographic Coding Interface is not available.
