Which statement is false regarding an ARRAY statement?

• A. It must contain either all numeric or all character elements
• B. It must be used to define an array before the array name can be referenced
• C. It can be used to create columns
• D. It is an executable statement

Answer: (D)

The statement that an ARRAY statement is an executable statement is not accurate because the ARRAY statement itself is classified as a declaration statement in SAS. Declaration statements are used to define elements, structures, or formats in a SAS program but are not executed like data manipulation or data processing statements. The ARRAY statement is essential for creating arrays that can hold multiple variables, either numeric or character, which means it must follow the requirement of containing all elements of one type. It also needs to be defined before any reference to the array name, ensuring that SAS recognizes the variables associated with the array throughout the data step. Moreover, while the ARRAY statement doesn't "create columns" in a traditional sense, it can facilitate the manipulation of data by allowing you to work with multiple columns simultaneously within a dataset.
