Dear statalist,
I wish to list the ID numbers of those individuals in my dataset that have at least one missing value out any six variables (x1-x6). At the moment I have used the following logic: 
 
list responder_status ID if  x1==. | x2==. | ///
x3==. | x4==. | x5==. | x6==.

But I'm not sure if this is correct, so I did the following which I think is.

gen miss=0 
recode miss 0=1 if x1==.
recode miss 0=1 if x2==.
recode miss 0=1 if x3==. 
recode miss 0=1 if x4==.
recode miss 0=1 if x5==.
recode miss 0=1 if x6==.


However is there a more succinct way to write this code, instead of 7 lines?

Thanks in advance 
Sham
