Hi Helen,

> You mean char(1), right? How can you have a varchar(1)?

With varchar(1), the length of the strings entered can vary all the
way from 0 to 1. For a mathematician, there's a whole universe waiting
to be explored there :-)

OK, char would be better here. But AFAIK varchar(1) is legal; I might
have even used it myself in my younger days (and got away with it).
