Yet another SQL newbie question

My fellow geeks:
My SQL project is progressing nicely, but I've run into yet another place where I'm at a bit of a loss. 
I need to be able to UNION or INTERSECT an arbitrary 
number of identically-structured files, and I need to, at 
times, EXCEPT records from that intersection or union, 
based on the records in yet another identically-structured 
file.

I note that AS/400 SQL, at least at V4, has a UNION, but 
not an INTERSECT or an EXCEPT. Can anybody suggest where I 
should be looking for an alternate way to do this?
