Correct me if I am wrong, but the PURPOSE of KEYWORD_SET is to check if
a KEYWORD is SET. Settable keywords are those that you either set or
don't, either /K_SET or K_SET=0. As such, they should not be set to
arrays. As far as I can see, Keyword_Set is a convenience function. For
value passing keywords, N_elements should be used.
So, it looks to me that the name of this function means exactly what it
is designed for.
Cheers,
Pavel
