Another way to do it 

gen byte newvar = cond(missing(var), . , var > .5) 


Martin Weiss

As always with the "greater than" operator in Stata, special care should
taken with regard to missings. So my expanded advice for you would be to
explicitly account for them:

set obs 10000
gen var=runiform()
su var

//introduce missings
replace var=. in 5/8
ins var

//explicity deal with missings
gen byte newvar=var>.5 & !mi(var)
ta newvar, mis

l in 1/10, noo

Martin Weiss

replace var=var>.5

I got some very good quick advice on a looping question I asked 
earlier.  I have another question.  Suppose I have a variable with 
values that range between 0 ands 1.  I simply want to recode this so 
that any value greater than 0.5 becomes a 1, and 0 otherwise.  How do I 
do this?
