Ada95 input output - simple question from novice

[winn@ist.flinders.edu.au (Tiffany Rose Winn)]

I want to use a simple put statement to display an integer in 
a minimum number of spaces: for example,

    count: integer:= 5;
    put(count, 2);

I thought the above statement would display the integer variable
count in a minimum of two spaces, but I keep getting an error saying
that my second put parameter is invalid.  

My guess is that this may be because the Ada compiler is using the 
put for characters, so I tried adding the line 
    package Ada.Integer_Text_IO is new Ada.Text_IO.Integer_IO(Integer);
just after the declaration of my main procedure, and also changed
the relevant put statement to
    Ada.Integer_Text_IO.put(count, 2);  
This gave me the following error:
    child unit allowed only at library level

I'm stuck as to where to go next (moving the package declaration to just 
below the "with Text_IO" line gave me errors, too).

Can anyone help?

Thanks in advance for your time.
