I have a situation in which it is not practical to use the debugging  
possibilities of GNAT GPS. Instead I want to use the Put procedure to 
show certain values.
Normally that is no such a program with the Predifined Language 
attributes (mostly with the 'image attribute).
Now I have the following:

type Buffer_Pointer is limited private;

    type Block_Buffer is record
       nr       : integer;
       buf      : Item;
       previous : Buffer_Pointer := null;
       next     : Buffer_Pointer := null;
    end record;

       El  : Buffer_Pointer := LastBuffer;
       El1 : Buffer_Pointer;

I just want to see if the routing of thedifferent Buffer_Pointer's is 
correct so I thought Buffer_Pointer'Image(El) would show the value of 
The Pointer El f.i. ?x000000 for null or even the simpel decimal value 0.

This construction creates a failure during compiling.
Should I use another attribute or some other construction?
