Step-by-Step Programming with Base SAS 9.4

Concatenating Data Sets By Using the APPEND Procedure

Understanding the APPEND Procedure

The APPEND procedure adds the observations from one SAS data set to the end of another SAS data set. PROC APPEND does not process the observations in the first data set. It adds the observations in the second data set directly to the end of the original data set.

The APPEND procedure has the following form:

PROC APPEND BASE=base-SAS-data-set <DATA=SAS-data-set-to-append> <FORCE>;

base-SAS-data-set

names the SAS data set to which you want to append the observations. If this data set does not exist, then SAS creates it. At the completion of PROC APPEND, the value of base-SAS-data-set becomes the current (most recently created) SAS data set.
