| BY-Group Processing in the DATA Step |
You can invoke BY-group
processing in both DATA steps and PROC
steps by using a BY statement. For example, the following DATA step program
uses the SET statement to combine observations from three SAS data sets by
interleaving the files. The BY statement shows how the data is ordered.
data all_sales;
set region1 region2 region3;
by State City Zip;
... more SAS statements ...
run;
This section describes BY-group processing for the DATA
step. For information about BY-group processing with procedures, see
Base SAS Procedures Guide.
