I believe the final answer is B), index is the correct function to use for this keyword search.

That makes sense, so we can eliminate D) as a possibility.

I'm not sure, but I think answer D) is incorrect because indexw is used for word searching, not substring.

I agree with because the index function searches for a substring within a larger string.

Yeah, FIND could work too. But I think INDEXC is a bit more straightforward and easier to read in the code.

Hmm, I'm not so sure. What about FIND? Doesn't that do a similar job to INDEXC?

You make a good point. I think I agree with Mirta that INDEXC is the way to go here. It's specifically designed for this kind of validation task.

Hold up, wait a minute. Isn't INDEXC different from INDEX? I thought INDEX just checks if the string contains the substring, not whether the entire string is valid.

Option B is the correct one. It uses INDEX to check if 'ABC' is present in TRT.

So, which option would correctly identify invalid values in the variable TRT?

Yes, you're correct. INDEXC is used to check if the entire string matches a set of characters. In this case, 'ABC'.

Yeah, that's how I understood it too. I think the best way to do that would be to use the INDEXC function, which checks if the string contains any characters that are not in the specified character set.

Hmm, this question seems pretty straightforward. I'm guessing the valid values for TRT are 'A', 'B', and 'C', and we need to find the invalid ones, right?
