Usage Note 22158: Does PROC APPEND process all the observations in the BASE= and DATA= data sets?
No, PROC APPEND performs an update in place on the BASE=
data set; therefore, it just adds the observations from the DATA= data set to the end of the BASE= data set. The observations in the BASE= data set are not read or processed. This means that PROC APPEND is more efficient than using a DATA step with a SET statement to append two SAS data sets.
