Not find an empty variables
In my exported data (xls, txt, SPSS), I do not see all my empty variables (all variables that contains no data). I know this is not very important because they are empty, but it is important for me to find them in the dataset. Because it blocks the automatic execution of my programs written in Stata, or other language statistics.
I think anyone can help me solve these problems. My English is not good, but I think you understand me.
