hmm,

it looks like it would work though :) . sure there are many ways, probably some drop if with and/or and all variables would also work...
i just thought there's a syntax that drops all missings directly. in a way this is what neil suggested....

thx everybody!!

Woops, my suggestion will only work after you recode -1 to missing.

...I have no knowledge of R, but it sounds like this is one (of many) ways to get what you want:

gen byte touse=1
markout touse var1 var2 var3

will create a variable named touse which contains 1s for cases with no missing values in var1, var2, or var3, and zeros otherwise. You can then use -if touse- after most commands or just -drop if touse- to actually drop them from the dataset.

HI everybody,

i have several non-response in my dataset that are coded -1 .
iŽd like to drop any observation (row) where one or more columns contains a -1.
