The other possibilities will be covered in subsequent All of the modification statements we will discuss can be used with any combination of input and of A data StepA data step that creates a single output SAS data set by modifying a single input SAS data set has a five part data statement to start the step and name the output data SET statement to read an observation from the input data statements to perform the processing required for this OUTPUT statement to write the observation to the output data set5.
