text_io append WinNT-oa+gnat

[Peter Hermann]

A small piece of experience given to AdaTeamers,
who work with portable software on different platforms:

The following holds for both ObjectAda7.1.1(Aonix) and GNAT3.10p
under WindowsNT4:

I have a small application, which (text_io.open) opens an existing
text file in append-mode.
This works fine, when the data file has an origin of DOS or Windows.
If not, i.e. when the data file comes from an unix-system,
there are problems with an additional empty line near the appended line.

Result:
Unix text data files need a conversion to dos-format when APPEND is used.

I did this conversion by means of textpad--tools--Convert_to_DOS,
but I guess there must be many other tools to convert from unix
to dos file format, aren't there?
A simple edit step in the ms-dos-editor and a forced save does this too.
