My understanding, which could be totally wrong, is that the major concept of "64 
bit" is about addresses.

So, even something using solely 64 bit addresses could still have multiple sizes 
of data types.  If using RMS, which I mainly do not, one would use the data 
types that RMS requires.  The concept would be for just about everything, use 
what the tool/app/whatever requires.
