Hi Jade!  You can use global variables within your service program to store
status about what files are open.  Alternatively, use the %open BIF.  Set
the variable at open time, and test it or the BIF at cleanup time.

That's easy enough as long as everybody understands that the files are open
until EOJ.

It's basically the same as #2, except that the files will be open a little
while longer  (until the caller goes to LR.)
