Which of the following correctly produces a title in which the current date is left justified in order to remove extra blanks?

  1. title "Report for %sysfunc(left(%sysfunc(today(),worddate.)))";

  2. title "Report for %sysfunc(left(today(), worddate.))";

  3. title "Report for %sysfunc(left(%qsysfunc(today(), worddate.)))";

  4. title "Report for %left(today(), worddate.))";

C Correct answer
Explanation

To left-justify a date in a title, use %SYSFUNC with LEFT function. Option C correctly nests the functions: %SYSFUNC(left(%qsysfunc(today(), worddate.))). The %qsysfunc gets today's date (with worddate. format), and left() removes leading blanks. The outer %sysfunc executes the left() function. Options A and B are incorrect in their nesting, and D is malformed.

AI explanation

To answer this question, you need to understand how to format a title in SAS using the %sysfunc function to manipulate the current date.

Let's go through each option to understand why it is correct or incorrect:

Option A) title "Report for %sysfunc(left(%sysfunc(today(),worddate.)))"; This option is incorrect because it uses an unnecessary nested %sysfunc function. The left function should be applied directly to the result of %sysfunc(today(),worddate.) to left justify it.

Option B) title "Report for %sysfunc(left(today(), worddate.))"; This option is incorrect because it does not use the proper syntax for the %sysfunc function. The %sysfunc function should be used with a specific SAS function, such as date. or left..

Option C) title "Report for %sysfunc(left(%qsysfunc(today(), worddate.)))"; This option is correct because it uses the %sysfunc function with the left function to left justify the result of %qsysfunc(today(), worddate.). The %qsysfunc function is used to resolve any potential macro quoting issues.

Option D) title "Report for %left(today(), worddate.))"; This option is incorrect because it does not use the %sysfunc function to manipulate the current date. The left function should be used within the %sysfunc function to left justify the result.

The correct answer is C. This option is correct because it properly uses the %sysfunc function with the left function and the %qsysfunc function to left justify the result of %qsysfunc(today(), worddate.).
