Explanation of Macro and Macro Function in SAS

In SAS, a macro is a reusable snippet of code that can be invoked using the %MACRO and %MEND statements. It allows for automating repetitive tasks and making the code more modular and flexible.

On the other hand, a macro function in SAS is a macro program that is designed to return a value. It is invoked in a similar way as a regular macro, but it is used to perform calculations or data manipulations and return a result.

Therefore, the main difference between a macro and a macro function in SAS is that a macro is used for code generation and automation, while a macro function is used to perform computations and return a value.
