Thanks Nick but I am not sure if I am getting it right. The 'd' is among the variables just likje a b or c but a b and c do not have missing values and in a way are unique. So imagine that my variables are labelled 1-50 and 1-3 do not have missing values, then starting with variable 4 to variable 50 I want all the 1-3 that have missing values in variables 4 - 50 but one at at time in a single command. I want 1-3 listed for missing values in 4, 5, 6 etc one at a time.
