SAS Base Latest Interview Preparation (Q&A)

Question-: Which procedure we can use to check the descriptor information?
Answer: We can use ‘CONTENTS’ procedure to print the descriptor information about the Data sets.



Question-: New Dataset is created after compilation or execution?
Answer: Compilation step checks the errors, type information of the variable and creates PDV etc. It does not write any observation; new observation would only be written when execution phase started which process each record as a time.



Question-: As soon as execution phase completed two automatic variables _N_ and _ERROR_ also stored with the output Datasets?
Answer: No, these two variables are not stored with the newly created output Datasets.



Question-: The format to the variable is applied once the variables are added in the PDV during the execution phase?
Answer: No, the formats for each variable are applied before the SAS adds the values to the PDV. Even before each iteration PDV is reset to missing values.
