Depends on how wide a range of hardware and OS you mean by "portable". The Ada language tries hard to be portable to no OS, hardware that has 39 bit "bytes", hardware that has ones-complement integer arithmetic, etc. If you restrict "portable" to mean an OS with a TCP stack, and hardware with 8 bit bytes, things are much simpler. In fact, the code you wrote is probably portable among that set. -- -- Stephe
