I considered doing it both ways, but decided that I preferred the slight 
space impact of being able to get to any fixed field by looking at only 
two numbers instead of all the preceding fields. I'm open to doing just 
lengths if people are very sensitive to the size of each record, but 
have a personal preference for what's in the draft currently.
