Methods of Combining Sas Datasets: Concatenation(set statment), Merge Statement:
Concatenating combines two or more SAS data sets, one after the other, into a single SAS data set.
- Use the SET statement in a DATA step to concatenate SAS data sets.
- Any number of SAS data sets can be read with a single SET statement.
Merging combines observations from two or more SAS data sets into a single observation in a new data set.
