Seems a bit naive to assume the address bus will always be the same width as the registers, but I guess the compilers have to do something.
I seem to remember some compilers allowing pure 32 bit addressing on 8088 machines (with 16 bit registers), but I think the M$ compilers all had near and far pointer mechanisms to help you get confused. -mumbling-ly yrs- Robin Becker -- http://mail.python.org/mailman/listinfo/python-list
