there is still a possibility of a silent loss of data.
This would only be an issue in following cases:
a) A class has more than 255 backward compatible versions. b) An archive has more than 64K different classes in it.
It is currently inconcievable to me that such a program would ever be written. Setting the sizes of these types to larger values would make every single binary archive bigger and slower.
a. Don't underestimate the potential of systems that generate code to... generate code ;-), including new versions of a class b. There are variable-length number formats that would allow you to avoid a size increase while still accomodating arbitrarily large version numbers. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
