Upgrading the DDL
The DDL is provided with some of the UNICOM Intelligence products.
You might want to visit the UNICOM Intelligence download site from time to time, to check whether a new version of the DDL has become available. This is particularly true if your version of the DDL came with one of the UNICOM Intelligence products, because a new version of the DDL sometimes becomes available between releases of the UNICOM Intelligence products.
