In theory, C, with a bit of help from the pre-processor, hides all the strangeness. You still hit bumps every now and then. (Byte order is an example, see the little-endian PPC port, but there can be other issues.) --Joel Rees Computer memory is just fancy paper, CPUs just fancy pens. All is a stream of text flowing from the past into the future.
