Subject:      How to check if dataset has any obs or not
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

I am working on program where I need to make one dataset (set them ) out of
10 datasets. I  need to pick datasets with observartions. How can I check if
a dataset has any observations if it has then I need to set it to another
dataset.

sample code is

   data all ;
     set a b c d e f g h i j ;
run;

if  b c  do not have data I do not want to set them. For this
1) I need to find if the dataset is empty or not then  with out opening them
then
2) set them to all dataset .

How can I do this .

thanks for the help
