+   --  String data for print out. The Pchars array is a long string with the
+   --  the entry for each node type consisting of a single blank, followed by
+   --  a series of entries, one for each Op or Flag field used for the node.
+   --  Each entry has a single character which identifies the field, followed
+   --  by the synonym name. The starting location for a given node type is
+   --  found from the corresponding entry in the Pchars_Pos_Array.
+
+   --  The following characters identify the field. These are characters
+   --  which  could never occur in a field name, so they also mark the
+   --  end of the previous name.
