st: systematically creating new observations

[daphna <bassok@hoover.stanford.edu>]

Hello-

I am wondering if anyone can recommend a way to systematically create 
observations.

Suppose I have a set of observations that looks something like this:

#Points
Female415896
Male420897


What I want to do is create a new observation (not a new variable), called 
ALL so that the data would look something like this:

#Points
Female415896
Male420897
All8351793


Of course, I need to do this more than once.  I have to do it for thousands 
of groups.

Is there a systematic way to add such an observation?

It seems pretty obvious but I cannot seem to figure it out.

Thanks so much for your help.

D
