36 -- In Ada 95, the package Ada.Text_IO.Decimal_IO is a subpackage of Text_IO.
37 -- This is for compatibility with Ada 83. In GNAT we make it a child package
38 -- to avoid loading the necessary code if Decimal_IO is not instantiated.
39 -- See routine Rtsfind.Check_Text_IO_Special_Unit for a description of how
40 -- we patch up the difference in semantics so that it is invisible to the
44 type Num
is delta <> digits <>;
