Hi all,

 

I used proc append to add observations from one sas data set to the end of another sas data set. However, I noticed the size of new dataset is much bigger than the sum of three adding data sets. I thought the size should be around the sum of three. Is there something wrong with the code?

 

 

data d.rat15to17; set d.rat15; run;
proc append base=d.rat15to17 data=d.rat16; run;
proc append base=d.srat15to17 data=d.rat17; run;

 

Thanks,

Chloe

A difficult question to answer without knowing the data. 

 

Are the variable lengths equal? Are any of the data sets compressed?

Thank you for the answers!

The variable lengths are different and I checked I didn't compress the data in the new files which caused the size difference.
