Because the file might have been transferred from another machine, and have the wrong byte-order for the current machine in the version 3 entries. The version 4 entries are portable, so they don't have this problem. It probably would have been better to just put a per record byte order maker in there, instead of using a version number, but you would still have the same problem for the records without the marker, so you'd have to ignore them as "suspect". -- TerryReceived on Tue Apr 29 2003 - 10:14:41 UTC
