Assuming that you began your SAS session today, which of the following statements correctly sets the macro variable currdate to today's date?

  1. %let currdate = %sysfunc(today(), worddate.);

  2. %let currdate = &sysdate9;

  3. %let currdate = %sysfunc(date());

  4. all of the above


Correct Option: D

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) %let currdate = %sysfunc(today(), worddate.); This option is incorrect. The %sysfunc(today(), worddate.) function is used to return the current date in word format, but it is not the correct syntax for setting a macro variable.

Option B) %let currdate = &sysdate9; This option is incorrect. The &sysdate9 macro variable is used to return the current date in the format ddMONyyyy, but it is not the correct syntax for setting a macro variable.

Option C) %let currdate = %sysfunc(date()); This option is incorrect. The %sysfunc(date()) function is used to return the current date in SAS date format, but it is not the correct syntax for setting a macro variable.

Option D) all of the above This option is correct. None of the previous options correctly set the macro variable currdate to today's date. Therefore, none of the options are correct.

The correct answer is none of the above.
