Combining Multiple Datasets in SAS

When dealing with multiple datasets in SAS, the primary method to merge or combine them is using the "MERGE" statement in the DATA step.

Using the MERGE Statement

The "MERGE" statement allows you to combine datasets based on a common variable. Here is a simple example:

```sas
DATA combined_data;
MERGE dataset1 dataset2;
BY common_variable;
RUN;
```

Replace "dataset1" and "dataset2" with the names of the datasets you want to combine, and "common_variable" with the variable that exists in both datasets and serves as the key for merging.

Remember to carefully consider the structure and contents of your datasets before merging to ensure accurate results. Practice concatenating datasets in SAS to better understand how to efficiently combine data for your analytical tasks.
