Question: 1 / 400

How do you utilize arrays in a DATA step?

Arrays are used only for character variables.

Arrays allow the manipulation of multiple variables through a single name in a DATA step.

Utilizing arrays in a DATA step allows for the manipulation of multiple variables through a single name, which enhances both clarity and efficiency in programming. This is especially useful when performing repetitive operations on a series of related variables.

For instance, if you have a dataset containing exam scores for several subjects, you can define an array to represent those scores. By referencing the array, you can perform calculations, such as computing the average score or determining which score is highest, without needing to repeatedly specify each variable. This simplification not only reduces the potential for errors but also makes the code easier to read and maintain.

Thus, option B captures the essence of how arrays function in SAS programming, enabling streamlined processing of a set of variables as a cohesive unit rather than individually.
