That's fine with me.  I've been mulling the possibility of creating a
typedef for case numbers, so that we could easily change them to unsigned
long long later--I suspect that >4G cases is not impossible, although
uncommon.

BTW, my responsiveness will be poor for a few days because of a hard disk
failure last Friday.  I don't expect I've lost any actual data, because I
back up obsessively, but it'll take IBM a few days to ship me a replacement
hard drive for my ThinkPad, and then reinstalling can take a little while
too.
