    The answer is D. Since you define variable style in the input statement before the if statement, you will have 7 variables.

    Hi Anonymous,
    The answer is B, because once you tell sas some condition as we have here if style = 'CONDO' or style = 'RANCH'; then it want do anything else.

    Agreed. The answer is not "D", it's B. 'If' is defined after defining the style variable, but it is defined before all the other variables (ie., sqfeet, bedrooms baths street etc.).

    It is B. That is a "Subsetting IF" statement. Notice that there is no "THEN" part to it. Since "OUTPUT" is implied before "RUN", only observations that make it past the subsetting IF will be output.

    ANSWER IS D

  16. The answer is D. 7 observations will be made because the style variable is defined before the IF statement. However, only 3 of those observations will be complete with all variables.

    1. The output will be
      RANCH,1250,2,1,Sheppard Avenue,"$64,000"
      SPLIT
      CONDO,1400,2,1.5,Market Street,"80,050"
      TWOSTORY
      RANCH,1500,3,3,Kemble Avenue,"$86,650"
      SPLIT

      This is an example of a subsetting if statement as part of a data step and has its own special syntax and meaning.

      Any observation failing the if condition will not be output.

      Thus, B and only 3 observations

    The subsetting IF statement (ie IF statement without 'then') causes the DATA step to continue processing only those raw data records or those observations from a SAS data set that meet the condition of the expression that is specified in the IF statement. That is, if the expression is true for the observation or record (its value is neither 0 nor missing), SAS continues to execute statements in the DATA step and includes the current observation in the data set.
    If the expression is false (its value is 0 or missing), no further statements are processed for that observation or record, the current observation is not written to the data set, and the remaining program statements in the DATA step are not executed. SAS immediately returns to the beginning of the DATA step because the subsetting IF statement does not require additional statements to stop processing observations.

  18. Answer is D guys. There is no output or delete statement. So when the if condition does not satisfies the observation will have only style and the other variables will be set to missing.
