gen newvar=var1
replace newvar=var2 if newvar==.
(you can also exchange var1 and var2; it depends on what you want)

Thank you to everyone who answered my last question on
creating a variable corresponding to the row number.
Now I have a question about combining the data from two
variables (in the same data set) into one variable. I want to
combine the variables in such a way that the data from one
variable can replace the missing values from the other. I have
created an example of what I am looking for below:
           Have:                   Want:
      var1       var2              newvar
        .          2                 2
        .          8                 8
        .          0                 0
        7          .                 7
        3          .                 3
        .          .                 .
Any thoughts on how to do this? 
Thanks
Eleanor Friedman
