SAS - Macros

Macros are powerful tools used in SAS code which allow the execution of generic code applied to specific tables.

• Macro variables

&name; /* Macro variable */
%name; /* Use of created macros or system macros */

Example:

%let city = "Barcelona";
TITLE "City: &city";

• Generation of code by using macros

%macro b;
a
%mend;

proc print data=%b;
run;
