• Question 117:

  Consider the following SAS log:

  229 data sasuser.ranch sasuser.condo / view = sasuser.ranch; 230 set sasuser.houses;

  231 if style = 'RANCH' then output sasuser.ranch; 232 else if style = 'CONDO' then output sasuser.condo; 233 run;

  NOTE: DATA STEP view saved on file SASUSER.RANCH. NOTE: A stored DATA STEP view cannot run under a different operating system.

  235 proc print data = sasuser.condo;

  ERROR: File SASUSER.CONDO.DATA does not exist.

  236 run;

  NOTE: The SAS System stopped processing this step because of errors.

  Which one of the following explains why the PRINT procedure fails?

  A. SASUSER.CONDO is a stored DATA step program.

  B. A SAS data file and SAS data view cannot be created in the same DATA step.

  C. A second VIEW=SASUSER.CONDO option was omitted on the DATA statement.

  D. The view SASUSER.RANCH must be processed before SASUSER.CONDO is created.
