The Add function adds segments to a database from an input data file. The database is not re-initialized. The Add function does not perform a Zeroload of the database. This is intended for adding additional data to a database or refreshing some of the segments in the database.
The Add function is not intended for initial loading of a database, part of a database reorganization, or for reloading a database after changing the DBD definition.
When running IMSBDU from the command line, the function-id to use for the Add function is ADD.
