   A modification made within the development environment will generate an
   application that contains all the possible implementations.

   In certain cases, it may be necessary to make the modifications from
   outside the code generator, directly on the sources. This helps also, for
   example, to obtain a global view of the entire source or to move parts of
   the code to another part, thanks to the the possibilities offered by
   modern text editors.

   The highly modular and architectural structure of the generated sources
   allow the programmer to add all the necessary customisations easily. It is
   also possible to use external procedures developed previously. This gives
   the programmer a great amount of freedom and flexibility for the
   development of complex applications with options not provided by the
   system.

   The programs in source format generated by dBsee are structured to allow
   the programmer to easily identify the main points of the functional flow,
   for adding parts of source code.

   The modifications made to the sources can contain Clipper commands, calls
   to functions defined in the list of Symbols or contained in the libraries
   provided with the generator. It is also possible to use the functions
   defined externally to the project. To do so, make sure that the library or
   the source that contains them is included among those to be called during
   the link phase.

   The final product modified in this way will have properties and
   functionalities different in comparison to those obtainable from the
   information contained in the project repository.

   In order to be able to generate a product with new details, from within
   the the development environment, it is necessary to invert the information
   flow: from the final product to the generator and not from the generator
   to the final product. The generator must be instructed on the
   modifications made to the sources that make up the application.

   The operation used is called Reverse Engineering. The process reads
   the sources modified manually and to brings such coded modifications
   within Project Repository.
