Ada95 input output - simple question from novice

Ada95 input output - simple question from novice

[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.

Forget about trying to instantiate integer_io until you understand
generics better. Meanwhile (since you are clearly using an Ada 95
compiler, probably GNAT), use:

with Integer_Text_IO; use Integer_Text_IO;

now your original put will work fine, because Integer_Text_IO provides
a put for type Integer.

Correction: that should be

with Ada.Integer_Text_IO; use Ada.Integer_Text_IO;

Just drop the 'Ada.' in the new package name:
   package integer_text_io is new ada.text_io.integer_io(integer);
