   --  types declaration and dispatching calls

   procedure Initialize;
   --  Called at the start of compilation to initialize the table that stores
   --  the tree nodes used by Generate_Output. This table is required because
   --  the format of the output requires fully qualified names (and hence the
   --  output must be generated after the source program has been compiled).

   --  type declaration
