Hi Marcia, as Bob said, if you could change your library names, that's the
way to go.  If you can't, (I will try to explain this but this could work
depending on the application), you could use member in your actual files and
use the same library and files, this will cost a little on performance but,
on your entrance program you will have to do a ovrdbf to all the files on
your library.  (This could work only if the application allow it).  BE
REALLY CAREFUL, you are going to be using the same objects so if the
program's delete and object you will loose both environments
