scan(string,n,) - returns the nth “word” in string

The statement is TRUE. This describes the SCAN function as implemented in SAS: SCAN(string, n, ) returns the nth 'word' (token) in the string, where words are the pieces separated by the specified (or default) delimiter characters. The third delimiters argument is optional; when omitted, SAS uses a default set of delimiter characters. A negative n counts words from the right end. The signature and behavior in the question exactly match the documented SCAN function, so the assertion is correct. The marked answer 'True' is right.
