Answer 1

The SAS macro facility offers the benefits of reducing program text, enabling easy modification and customization of code, and automatically referencing system information. The correct choice is (d) all of the above.

Step-by-step explanation:

The benefit of using the SAS macro facility includes several aspects:

• Reduction of text in programs: Macros enable you to reuse the same code multiple times without having to retype it. This makes your programs shorter and easier to manage.
• Easy modification and customization: By using macros, you can write general codes that can be customized by changing the macro variables. This allows for easy updates and adaptations to different data sets or requirements.
• Automatic referencing of system information: Macros can dynamically insert system information like date and time, file paths, etc., into your programs, which can be very useful for logging and tracking purposes.

Therefore, the correct answer is (d) all of the above, as the SAS macro facility provides all these benefits, making it a powerful tool in SAS programming.
