Comment:

 I'm still looking at this.

 I may be able to make changes to accomodate older archives which used a
 version # exceeding the originally expected 8 bits.  I expect to enforce
 the 8 bit expectation in the future to avoid these problems.  So you would
 be left with the capability of reading old archives, but the version
 number stored would have to be limited to 8 bits.  So class using the "old
 version numbers" would have to be enhanced to make the switch as they are
 loaded.  I don't know if this would be acceptable to you.
