Which statement is false concerning the following array statement: array TwoD[2,3] $ _temporary_?

The statement regarding the array declaration, "array TwoD[2,3] $ temporary," creates a temporary two-dimensional array with 2 rows and 3 columns, meaning a total of 6 elements are indeed created. This determines that six separate array elements exist in the program data vector (PDV).

When it comes to the nature of temporary arrays in SAS, these elements are automatically retained between iterations within the DATA step but will not be included in any output data set, which corresponds to the properties of temporary arrays. Because the array is temporary, once the DATA step is completed, its elements vanish and are not part of the final output table created.

In this context, the way to access elements in a two-dimensional array differs from a one-dimensional array. For the declared array, you need to reference elements using two indices because it has both row and column dimensions. Therefore, suggesting that the array elements can be referenced with a single number is inaccurate since a two-dimensional array requires accessing it in a row-column format (e.g., TwoD[1,2] to access the element in the first row and second column). This is why the statement about being able to reference one number is false.
