	And that IS the documented standard... Actually, you are lucky that the
new-line is all you see, as the standard would have the Close operation
ensure the file ends with: new-line, new-page, end-of-file (but does not
mandate how those states are represented in the file -- suspect EOF is
mostly handled as meta-data in the directory entry rather than an explicit
character)

	As has been mentioned, Stream_IO was sort of created for this role.
