SAS Interview Questions and Answers

Question: What is the purpose of the RETAIN statement in SAS?
Answer: The RETAIN statement is used in the DATA step to prevent the automatic initialization of variables to missing values at the beginning of each iteration.

Example:

DATA new_dataset; SET old_dataset; RETAIN variable1 variable2; /* Retains the values of variable1 and variable2 across iterations */ variable3 = variable1 + variable2; RUN;
