I should have mentioned that -merge- and -sum( )- are among the most
underrated command/functions in Stata.
 
They also happen to be Bill G.'s favorite tricks for cleaning data. It
comes up occassionally on this list, if you know what to look for.
 
Just so you know from whom I get these things from.
