The SET statement reads observations from one or more SAS data sets and uses them to build a new data set.

The SET statement for concatenating data sets has the following form:

SET SAS-data-sets;

SAS-data-sets specifies the two or more SAS data sets to concatenate. The observations from the first data set that you name in the SET statement appear first in the new data set. The observations from the second data set follow those from the first data set, and so on. The list can contain any number of data sets.

Using the SET Statement: The Simplest Case

In the simplest situation, the data sets that you concatenate contain the same variables (variables with the ...
