st: Comparing variables by observation

Hello Everyone,
Hello Martin,
I am facing the following problem: I have three variables X1 X2 X3
(taking values from 1 to 10) and I need to compare their values, by
observation, according to several conditions (which are theoretically
derived) of the form, examples: (1) 5>= X1 >=X2 >=X3 >=4; (2) X1<=3
and 5<= X3. I need to evaluate each condition on the data by counting
the number of times it is met, in order to classify the observations.
I tried several approaches, but the total number of classified
observations exceeds the total number of observations. So, I am
guessing I have some redundant counts - maybe I am doing something
wrong with the coding (given that the conditions are correct).
Thank you very much for your help and insights.
Anisa
