syntax - How to find VARIABLES with nothing but missing value? -

i know possible find cases nil missing values help of "select if nmss(v)=x"

but should if want find varibales missing values?

say have dataset else on hundert variables, variables finish missing values (in case, questions/varibales not asked durning interview), how can find thoses varibales in efficient way?

if have info preparation option, can utilize info > validation > validate info screen variables. if not, there function in spssaux2.py module (available spss community website - www.ibm.com/developerworks/spssdevcentral) called findemptyvariables this. requires python essentials.

here how utilize it. begin program. import spssaux2 print spssaux2.findemptyvars() end program.
