Right. Hence my question.

You mean use Address_To_Access conversion? Because what I have is C
pointers I need to interface with. I am using Chars_Ptr because it has a
Null_Ptr value and I need to test for, and pass, NULL. (And in C char *
is assuredly able to point to anything.) But I am indeed considering
using Address et al., and Address to Access conversion.
Yes, the ARM has a lot of nice implementaion _advices_ on this.
