Hi Statalist

I have a question about trying to drop those rows that are empty in all the variables of my dataset.

I understand this problem can be solved with:

Code:
 
 drop if missing(var1) & missing(var2) & missing(var3)
The problem I have close to a hundred variables, making this a very manual and laborious process. Is there any way to include a) all variables b) specified groups of variables at once?

Thanks.
