If that's what you meant by it, then that bit was correct. But "from will be the MSbyte, piece will be the LSbyte" is guaranteed only if you know the architecture the thing is being compiled for. Ascending address order needn't mean most significant byte first. In fact, on ia32 systems it's exactly the other way around, so if Zach's code is going to run on a PC then "from" will be the least significant byte and "piece" the most. Well, strictly even that isn't *guaranteed*, because: >>There may be padding anywhere within the structure, including >>between those single-byte fields. Not that this is likely to be a problem in practice, in this particular case. -- g
