About Datasets procedure and Data step

[ASJ]

Which of the following statements is true about techniques that are used for modifying data and attributes?

1. You can use PROC DATASETS to modify both data values and variable attributes.

2. You can use PROC DATASETS to modify only data values.

3. You can use the DATA step to modify both data values and variable attributes.

4. You can use the DATA step to modify only variable attributes.

For above question as in, SAS Advanced programming ver. 3 book in Chapter 22

The answer should be 3 however this book says 1. Can you please let me know the correct answer.

The right unswer is 3 - You can use the DATA step to modify both data values and variable attributes.

At most, 3 and maybe 4, as you can use data step to only modify attributes.

1 and 2 are false for sure... As far as I know it's not possible to change data values with proc datasets.
