I looked over Set_Output in the ARM and I went back looking for it in
the comp.lang.ada, and it looks to me that Set_Output will direct all
Put statements to Outfile if a file isn't designated, rather than
having calls of Put (Outfile, Item) appear in Standard_Output.

This doesn't appear to be the functionality I'm looking for.  If no
file is specifically named for Outfile, I want all output to appear on
the terminal.  If a file is named for Outfile, then direct output to
that.  Using Set_Output (Outfile), wouldn't I still need a Create
statement for Outfile?
