42

53
--  On return, the file is positioned either to the end of file, or to the
54
--  first character of the line following the SCO information (which will
55
--  never start with a 'C').

57
--  If a format error is detected in the input, then an exception is raised
58
--  (Ada.IO_Exceptions.Data_Error), with the file positioned to the error.
