Answer / manoj mishra
Make a library where all data set resides. Use proc contect
and out option to create a data of proc contect from where
we get all data set name. Create Macro using Call Symput for
each dataset name into separate macro variable. We can not
merge them as they dont have common variable. We need set or
Append or SQL to merge them together.
