Your last question is about intention -- what was in the mind of the
program designers -- and 
is perhaps best answered by StataCorp. Oddly enough, I've never used the
four argument case that
I can recall. Although some dislike the usage, nesting of -cond(,)- lets
you handle four or more
branches, and I find that more congenial, e.g.  

cond(x == 1, 1, cond(x == 2, 2, cond(x == 3, 3, 4))) 

Naturally there are many other ways to achieve similar results.

Thanks for the coding suggestions.  This is exactly what I was looking
for--especially for the multiple variables.  And, Nick (Winter), thanks
for the explanation for cond().  

One question: was it the intention of the 4-level cond() to code for
missings or is there some other application for it?
