Sorry- didn't see this. Thank you.
Is there any way to standardise the process so I can use a varlist and do not have to manually count the number of
variables in that list?

for negatives you can use
tempvar r
egen `r'=anycount(A B C),values(0)
drop if `r'==3
where 3 is the number of variables in your varlist specified in the
anycount function.

missings are treated as zeroes and things get more complicated if any
of the vars may contain negatives.

Hi,
Does anybody know how I can drop observations if a number of values are
zero?
I can do this by manually inputting drop if( A==0 & B==0 & C==0) But I was wondering if there was any easier way of
doing this (especially when I have a lot of variables)- perhaps using varlist somehow?
Many Thanks,
