No it cannot, since %p is an "implementation-defined" format specifier. Most 
importantly, if I want to use an integer I need an unsigned integer. Negative 
addresses don't make that much sense to me. Maybe with the new BITS features 
I can get this.

The "feature" is trivial. It is more work for implementors to prohibit C_PTR 
in I/O than to allow it....after all, "implementation dependent" means they 
can simply print a blank character if they are really that lazy.
Telling people to use horrid things like TRANSFER to do a simple task is, 
well, horrid...IMO, of course.
