Thanks for your clarification.
Personally I don't like it to keep files open when they are no longer
used. I'm thinking to create a serviceprogram to register
serviceprograms when they are opened (and then do an OpenFiles routine).
When a calling program is ending, it would call an unregister routine
that does a CloseFiles routine voor all registered serviceprograms.
By doing this I would ensure that I never forget to close files. But
maybe it's a little overdone to do such thing?

Best regards,
Arco Simonse
