how to set up variable(s) for one of multiple SAS data sets?

[tianerhu]

I have one SAS data set MM and want to create three SAS data set, A , B , C ,respectively.

There are six variables in SAS data set MM—— score1 , score2 , score3 , score4 , score5 ,score6 ;

if I want to set up one new variable, average = mean(of score1-score6), and put it into data set B  , how should I do ?

data A B C;

set MM；

The description of your needs is tenuous. This sticks to your script:

data A B(keep=average) C;
  set MM；
  average = mean(of score1-score6),
