Dear Vladimir:

You find at:


in the navigation tab "EpiData course", in Part B: Introduction to 
EpiData Analysis, Exercise 3: "Aggregating data and saving the summary 
data in a file" which gives you precise answers to your questions (if 
you don't want to do the exercise obtain the two PDF files for Task and 
Solution respectively, it should suffice).

You will note that EpiData Analysis exceeds Epi Info in power and 
efficiency in this respect as well.
