   The first phase when developing an application is the definition of the
   Data Dictionary: creation of files, relative fields, associated
   indexes and relations.

   To correctly set up an application's Dictionary, it is necessary to
   consider what data will be managed so that it can be organised in an
   optimal way, making the data easy to be retrieved and avoiding redundant
   information. From the main menu, press the Dictionary button. You will
   now be in the definition environment of the entities needed to create the
   database.

   The information contained in the Data Dictionary are relative to:

     . Files

     . Fields

     . Indexes

     . Symbols

     . Relations between files

     . Variables

     . User Defined Functions

   For each entity managed in the dictionary, a Definition Frame is made
   available for the setting and the modification of its properties. The
   Definition Frames can not only be accessed from within the Dictionary, but
   from within any other environment in which the entity is being used. It is
   possible to directly define the context Help, the Technical Manual and the
   User Manual for the application by simply inserting text comments in the
   Notes.

   The Dictionary environment is divided into three different frames
   (fig. 2-1). The main Frame, shown in the upper left part of the screen,
   contains a list of the Files. The name and the main properties relative to
   each of the files defined are shown. The frame next to the file frame
   shows the defined fields for the highlighted file, while the frame shown
   in the lower part of the screen contains a list of all the indexes set for
   the same file. Moving the cursor on another file will update the
   information regarding the Fields and Indexes within the other frames. In
   the Service-User environment, an option can be set for hiding or
   displaying these additional 2 frames.

   The following is a list of the different types of entities managed within
   the Dictionary environment.
