Is a reverse of PROC CONTENTS possible to create an EMPTY DATASET. I have created a proc contents dataset as follows: proc contents data=EMP out=EMP_OUT noprint; run; Now I updated the LENGTH of few columns in EMP_OUT using proc sql. Then I like to create the EMPTY DATASET having this updated LENGTHs and the rest of the attributes remain the same. After that I like to merge the EMPTY DATASET back to the original EMP. Basically, I am trying to update lengths of each of the variables accoring to its maximum value length in that variable. To reduce the size of the dataset.
