Stream-oriented I/O is unformatted per concept of. It is a stream of
elements, not even characters. Formatted I/O is when there are some things
beyond characters, like lines, columns, pages etc.
For formatted buffered I/O use strings. As a block/record/line use String.
You can find an example of string formatting library here:
http://www.dmitry-kazakov.de/ada/strings_edit.htm
For physical I/O, which is a separate issue, you can still use streams,
files, sockets, whatsoever. Just define a primitive operation Write_Line on
the abstract type of the "recipient," which takes String argument. For all
further types of objects use that primitive operation.
