How to save the predicted value of regressions

[Issa Almaharmeh]

Dear Statalists'
Can any one help me how to save the predicted value of many regressions.
I have to run 60 regression each year for 20 years.
I tried this code

by(industry_id year): reg y x1 x2 x3

then I use predict but I have no results.

ssc describe rangestat 
ssc install rangestat 
rangestat (reg) y x1 x2 x3, int(year 0 0) by(industry) 
gen double predicted = b_cons + b_x1 * x1 + b_x2 * x2 + b_x3 * x3

Many thanks for you. It works perfectly.
