Yes of course:

   C : access Integer;
   ...
   C := new Integer'(12);

I do not follow. The conversion will change nothing:

1. you allocate an anonymous access from a "compiler specific pool A"

2. you convert the anonymous access type to a named access type : NAT

3. you deallocate NAT from a "compiler specific pool B"

This will allocate and deallocate on different pool. And AFAIK there is
no way to specify the anonymous access type pool.

I don't see a solution to that problem at the moment...
or I'm confused :)

Pascal.
