Text_Io Questions

[tmcclory@valhalla.cs.wright.edu (Tom McClory)]

A few novice questions on using Text_Io ...

I've checked a couple of  "intro" text books on Ada, and the LRM, but I 
haven't found a solution to either of these (trivial?) problems.  I 
would welcome suggestion from any gurus in netland.  If there is 
sufficient interest, I'll post a summary.

1) How to open a text file to append to an existing text file?

2) Is there some way to write to either Standard_Output or to a file?
The Text_Io.File_Type is limited private, so the following doesn't work:

    The_File : File_Type;
    The_File := Standard_Output;
    ...
    Put(The_File, "hello world");

I then tried the following but the exception "Name_Error" was raised:

    Open( File => The_File, Mode => In_Out, Name => Name(Standard_Output));

I also tried Create, but this created a new file in my directory 
named "stdout".
