Dec 30, 2023 · SAS macros are reusable pieces of code. To define a macro, use %MACRO and %MEND. To call a macro, use %macro_name(parameters). Macros enhance code modularity and efficiency in SAS programming.

ATTRIB var <LENGTH=’var n -length’> <LABEL=’var n -label’> n <FORMAT= .> <INFORMAT= >; var n -format var n -informat. Associates a format, informat, label, and/or length with one or more variables . Indicates that data lines follow (suffix of 4 if data has ‘;’s).

We explain how the macro processor works, and how to use macros and macro variables. Using these techniques you can create flexible, reusable code that can save you time and effort. WHY USE MACROS? Because macro code takes longer to write and debug than standard SAS code, you generally won’t use macros in programs that will be run only a few times.

SAS Macro Functions. There are some SAS macro functions which help you to execute various operations within a macro. Below is a list of SAS Macro Functions. 1. %EVAL Function. It is used to perform mathematical and logical operation with macro variables. Example - %let x = 10; %let y = 20; %let z = &x * &y; %put &z; It returns "10*20".
