Use the SET statement to concatenate data sets.

Note:   Concatenating data sets is the combining of two or more data sets, one after the other, into a single data set. The number of observations in the new data set is the sum of the number of observations in the original data sets. The order of observations is sequential. All observations from the first data set are followed by all observations from the second data set.

The sequence of variables on the SAS data sets is immaterial. SAS matches variable names to append the DATA.

See also PROC APPEND in the SAS Procedures Guide.
