+   --  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.
+
+   --  Note the following definitions do not include Flag0. This will have to
+   --  be addressed if we ever need to use Flag0 (it's not currently used).
