  29 --  The Par function and its subunits contains all the parsing routines
  30 --  for the top down recursive descent parser that constructs the parse tree
  31
  32 with Types; use Types;

  34 function Par (Configuration_Pragmas : Boolean) return List_Id;
  35 --  Top level parsing routine. There are two cases:
  36 --
  37 --  If Configuration_Pragmas is False, Par parses a compilation unit in the
  38 --  current source file and sets the Cunit, Cunit_Entity and Unit_Name fields
  39 --  of the units table entry for Current_Source_Unit. On return the parse tree
  40 --  is complete, and decorated with any required implicit label declarations.
  41 --  The value returned in this case is always No_List.
  42 --
  43 --  If Configuration_Pragmas is True, Par parses a list of configuration
  44 --  pragmas from the current source file, and returns the list of pragmas.
