Question

which of the following actions occur at the beginning of an iteration of the data step? a. the automatic variables n and error are incremented by one. b. the values of variables created in programming statements are re-set to missing in the program data vector.

Answer 1

Option (A)

Step-by-step explanation:

The DATA step begins with a DATA statement. Each time the DATA statement executes, a new iteration of the DATA step begins, and the _N_ automatic variable is incremented by 1. SAS sets the newly created program variables to missing in the program data vector (PDV).
