Not being aware of your definition of DISTRESS I can't offer 
any checks here. 

gen distress = . 
replace distress = max(h3sp5, h3sp6, rr_h3sp7, h3sp8, h3sp9, h3sp10, rr_h3sp11, h3sp12, h3sp13) - 1 

looks like one equivalent of your code.

I am working on Add health data in Stata 9 and wish to create a single measure of DISTRESS using 9 identified variables all on a scale of 0-3. I have tried Stata's -generate- and 
-replace- command below but did not trust the results I obtained.
 
generate distress=.
replace distress=1 if h3sp5==0|h3sp6==0|rr_h3sp7==0|h3sp8==0|h3sp9==0|h3sp10==0|rr_h3sp11==0|h3sp12==0|h3sp13==0
replace distress=2 if h3sp5==1|h3sp6==1|rr_h3sp7==1|h3sp8==1|h3sp9==1|h3sp10==1|rr_h3sp11==1|h3sp12==1|h3sp13==1
replace distress=3 if h3sp5==2|h3sp6==2|rr_h3sp7==2|h3sp8==2|h3sp9==2|h3sp10==2|rr_h3sp11==2|h3sp12==2|h3sp13==2
replace distress=4 if h3sp5==3|h3sp6==3|rr_h3sp7==3|h3sp8==3|h3sp9==3|h3sp10==3|rr_h3sp11==3|h3sp12==3|h3sp13==3
 
I would be happy if I could obtain assistance to do this more efficiently. Will array code in Stata like is done in SAS be appropriate here.
