This is so far from being correct Ada that it's impossible to tell what 
you're trying to do, but I'd suggest you pull the instantiation of B_Pkg 
out of the procedure.

If you can provide a better example, with information such as the 
specifications of the packages and the definition of B_Pointer_Type, we 
can probably help you better. It's likely you don't need access types or 
values at all outside the packages; pointers are needed far less often 
in Ada than in C (compiler writers excepted).

Finally, "Ada" is a woman's name, not the American Dental Association 
(or other acronym). People on c.l.a get more or less upset with others 
who don't capitalize it correctly.
