Here are three different ways of achieving this goal:

*--------------- begin example ------------
sysuse auto, clear
sum mpg
gen byte d_mpg1 = mpg > r(mean) if mpg < .

gen byte d_mpg2 = 1 if mpg > r(mean) & mpg < .
replace d_mpg2 = 0 if mpg <= r(mean) & mpg < .

gen byte d_mpg3 = cond(mpg > r(mean), 1, 0) if mpg < .
*---------------- end example --------------
( For more on how to use examples I sent to statalist see:

Hope this helps,
Maarten
