Good question in light of the inadequate coverage of I/O issues in the 
Barnes Ada 95 text (pet peeve!). I discovered the following short-cut in 
the Ada95 for C/C++ on-line guide at  

http://lglwww.epfl.ch:80/Ada/Ammo/Cplpl2Ada.html

"A simple program below uses Text_IO to print a message to the screen, 
including numerics!
These are achieved by using the types attribute 'Image which gives back 
a String representation of
a value. 

with Ada.Text_IO; use Ada.Text_IO;
procedure Test_IO is
begin
  Put_Line("Test Starts Here >");
  Put_Line("Integer is " & Integer'Image(2));
  Put_Line("Float is   " & Float'Image(2.0));
  Put_Line("Test Ends Here");
end Test_IO;

It is also possible to use one of the generic child packages of Ada. 
Text_IO such as
Ada.Text_IO.Integer_IO which can be instantiated with a particular type 
to provide type safe
textual IO. 

with Ada.Text_IO; 

type My_Integer is new Integer;

package My_Integer_IO is new Ada.Text_IO.Integer_IO(My_Integer);
use My_Integer_IO;
