within ID. If ID corresponds to a person then, barring gender reassignment
surgery, sex should be constant throughout an ID.

       Dear Stata users,
       
       Currently I am working on a data set where I have to fill the gaps in
the data and then 
       do analysis. An example of the data is as follows:

       where for sex 1 is coded for males and 2 for females and for
employment status 
       (empstatus) 1 is employed and 2 for unemployed. Is there any fancy
command in stata 
       which can fill the gaps.
