st: percentile across variables

["silver.com@libero.it" <silver.com@libero.it>]

dear sirs, I have what probably it is a basic question but I cannot solve it. 
My database is formated as follows


ID                var1           var2            var3              
var4                   var... 
aa1              4                4.5              6.7                
0.5                     ....
atd3             6.5             3.1              7.2                
0.6                     ...
ujd2             9.5             6.1              2.9                
1.2                     ... 
..                    ...                 ...                
...                  ...                      ...   


The different variables are the measurement of the effect on the same 
treatment conducted in slightly different ways. What i would be interested to 
know is how to compute some descriptive statistics (percentile and averages) on 
how the same subject reacted to the different treatments. Otherwise said, i 
should calculate the descriptive statistic horizontally while variables are 
arranged vertically. Is this possible in stata?

Thanks a lot,
Jibo
