Is 0 the smallest possible value, and are all cases non-missing? (Or else missing for all 10 vars?) Then try

recode letter_auto_stop 0=1 if max(letter1,letter2,letter3,letter4,letter5,letter6,letter7,letter8,letter9,letter10)==0

Statalisters,

I have some code that I would like to make more elegant (shorter,
while still fitting on one line):
recode letter_auto_stop 0=1 if letter1==0 & letter2==0 & letter3==0 &
letter4==0 & letter5==0 & letter6==0 & letter7==0 & letter8==0 &
letter9==0 & letter10==0

The line above works, but it's bulky.  I'd like to find something
better to use.  I tried:
recode letter_auto_stop 0=1 if letter1-letter10==0

but stata treated it as "recode letter_auto_stop 0=1 if letter1==0 &
letter10==0" ignoring letter2 through letter9 entirely.

Thanks for any help you can provide!
-Michael
