If I have defined an object of Ada.Text_IO.File_Type, say My_File, I
can use Ada.Text_IO.Is_Open to find out whether My_File is associated
with a physical file.

However, if I have a string say "autoexec.bat", is there a function
that will tell me if I have a file already open of that name (i.e. if
the physical file is associated with an object of type
Ada.Text_IO.File_Type - effectively the opposite of what
Ada.Text_IO.Is_Open does)?

I'd be grateful for any pointers, I originally thought that
Ada.Text_IO.Is_Open would do what I want until I got an error on
compilation, when I decided I should look at the RM! (don't have a lot
of text_io used on satellite instruments where I work)

I couldn't find what I wanted but maybe I was looking in the wrong
place!
