I assume you have a list associated with the FILELIST, otherwise the
meaning of "service-area" is not defined. If so you can try:
*+ XYZ= Allow:Service
Note that this is a kludge ('Allow:' stands for LSVALLOW, obviously
you're talking about things you are allowing when you define a FAC :-) ).
It only works in 1.6 by the way.
