How do you append data in SAS?
PROC APPEND BASE=SAS-data-set DATA=SAS-data-set ; RUN; PROC APPEND adds the observations from one SAS data set to the end of another SAS data set. BASE= names the data set to which the observations are added, and DATA= names the data set containing observations that are added to the base data set.
Can you merge 3 datasets in SAS?
SAS Merge allows the programmer to combine data from multiple datasets. Each observation from dataset one is combined with a corresponding observation in dataset two (and dataset three, etc.)
How do I add two tables in SAS?
SAS concatenates data sets (DATA step) and tables (SQL) by reading each row of data to create a new file.

What is the difference between set and append in SAS?

How to append data sets in SAS-SAS example code?

Notice also that SAS still returns a warning if you try to append tables with different structures even though you use the FORCE option.
Why does the SAS append statement default to cntllev?
If the BASE= data set is accessed through a SAS server and if no other user has the data set open at the time the APPEND statement begins processing, the BASE= data set defaults to CNTLLEV=MEMBER (member-level locking). When this behavior happens, no other user can update the file while the data set is processed.
How to add observations to a SAS data set?
