/INSERT Use this qualifier to add one or more definition modules to an NCS library. If the input file(s) contains more than one definition, NCS creates a separate entry in the library for each. Before NCS inserts a definition into an existing NCS library, it verifies that the library does not already contain a definition module having the same name. If NCS finds a definition module with the same name, it does not add the new definition module to the library but it does issue an appropriate error message.
