Hello all, I have 10 datasets going from input1 to input10. Then I want to transform them to iml data so I can do complex matrix calculations. The problem is that I can loop over the datasets with &i. as the variable suffix part. But I do not know how to loop over them when they are iml data, is it possible to do this in iml or is it just not possible? proc iml; %MACRO DO_BRANCH; %do i=1 %to 10; use input&i.; read all var _ALL_ into imlData&i.[colname=varNames]; close input&i.; %end; %end; %MEND DO_BRANCH; %DO_BRANCH; %The code below does not work !! do i =1 to 10; imlData&i.[1,1] = assign a new complex value (not important); end; If anybody knows the answer please tell me :), thank you all!
