Option A all the way! It's the only one that specifically checks for characters outside of the valid set. And hey, who needs 'index' when you've got 'indexc'? It's like the SAS version of a Swiss Army knife.

D is an interesting choice, but 'indexw' sounds like it might be checking for word boundaries, which isn't really what we need here. I'd stick with the more straightforward options.

Option C is a bit of a wild card. 'find' is not a function I'm familiar with in SAS, so I'm not sure if that's the right approach.

I'm going with Option B. 'index' is a classic way to check for invalid values, and it's easy to understand.

Option A seems legit, but I'm not sure why we need to use 'indexc' instead of 'index'. Wouldn't that work too?

Haha, I bet the person who wrote this question was having a field day coming up with these SAS functions. Time to break out the SAS manual!

I think option D is definitely incorrect, as indexw() function is used for word searches, not character searches.

I'm going with D. The INDEXW function checks if the variable contains the specified word, which seems like the best fit for this problem.

I'm not sure, but I think option A could also be correct because indexc() function is used to search for characters in a string.

Option B looks good too, but the INDEX function only checks for the presence of a substring, not the entire string. A more appropriate choice would be A.

Yes, option B only checks for the presence of a substring, so it may not be the best choice in this case.

I agree, option A is the correct choice because it checks for the entire string 'ABC'.

I think option A is the correct answer. The INDEXC function checks if the variable contains any characters that are not in the specified string, which is exactly what we need here.
