The package Text_IO.Streams allows a Text_IO file to be treated as a stream. Data written to a Text_IO file in this stream mode is binary data. If this binary data contains bytes 16#0A# (LF) or 16#0C# (FF), the resulting file may have non-standard format. Similarly if read operations are used to read from a Text_IO file treated as a stream, then LF and FF characters may be skipped and the effect is similar to that described above for Get_Immediate.
