That is besides the point because -egen, rowtotal- treats missings as 0
anyway. The point of the initial post was that we wanted a missing if any of
the observations being summed was missing.

The problem is that I need to distinguish when the resultant sum is cero or
a missing value. Do you know if there�s another command or function that may
sum by varlist and mantain the missing values when they are present?
