42 -- String data for print out. The Pchars array is a long string with the
43 -- the entry for each node type consisting of a single blank, followed by
44 -- a series of entries, one for each Op or Flag field used for the node.
45 -- Each entry has a single character which identifies the field, followed
46 -- by the synonym name. The starting location for a given node type is
47 -- found from the corresponding entry in the Pchars_Pos_Array.
48
49 -- The following characters identify the field. These are characters which
50 -- could never occur in a field name, so they also mark the end of the
51 -- previous name.

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