    Just my two cents on XL "feedback" from the system. I use XLs
extensively(most of my code is in XLs) and I would ALWAYS want to know when
an XL was not located if I directed the system to purposely include a
specfic XL in its resolution sequence. The NOWARN option is an accident
waiting to happen and should not be as such. The default should always be
WARN with the option of MUST for aborting if not found. I personally like
the "MUST" rather than the "+". "MUST" is instantly recognized and the "+"
could have many different connotations. I believe the most important aspect
the default "WARN" status is that you will ALWAYS know if a "directed"
specific XL was located or not(It will be right there on your Stdlist...!).
