First off, let me repeat some basic points 
stressed many times on this list. 

The language we are discussing is called Stata. 
Getting the spelling right may not matter to 
you but it irritates some of the people who 
might otherwise answer your questions and thus 
increases the probability of your postings 
being zapped by experts. 

You have Stata 8.0. As has already been mentioned, 
you should -update- to Stata 8.2. 

Now on the question: 
I have read your email but am not clear on what
your data in memory in Stata actually are. Two extreme
hypotheses seem consistent with your description 
here, that you have not yet entered the
data, and that you have 2 variables and 115 
observations in memory. 

Either way, commands you should find useful, 
at least in future, are -expand- and -reshape-.
