The DS2 language, which is another proprietary SAS programming language included in BASE SAS, plays an important and vital role in the processing of data where it is stored. This is especially true in cases where SAS data step logic can be transformed into DS2, which that logic to run in environments where DS2 is supported and the SAS data step is not.
