: How do I equate the general purpose System.Address to the PString?

Assume:

    String_Ptr : PString := new string'("Hello" & Ascii.Nul);

from String_Ptr to System.Address:

    tempAddr   : System.Address := String_Ptr(String_Ptr'FIRST)'ADDRESS;

from System.Address to String_Ptr:

    Don't.  It won't be portable.
