I have data sets like
AD_11  AD_12 ........AD_110
AD_21  AD_22.........AD_210
................................................
AD_111  AD_112.........AD_1110
Each data sets have single observation
Now I want merge data sets AD_11 AD_12  AD_13 ..... AD_110  into data set AAD_1
similarly AD_21 AD_22  AD_23..... AD_210  into data set AAD_2
For this purspose I m using following sas program
data _null_;      
     do j=1 to 11; 
          call execute(cats('data AAD_',put(j,8.),';')); 
          do i = 1 to 10; 
          sk=catt(j,i); 
          skn=inputn(sk,'6.',6,0); 
          call execute(cats ('set AD_',put(skn,8.),'; rename COL1=A;' )); 
          end; 
end;                                                                                                                                                                                     run;   
But when I run this program then for inner do loop ( i) it reads 10 obs from 10 data sets AD_11 to AD_110 but save only single value to AAD_1, however it should save all ten observation to AAD_1
