OK - the ISC4.gdb is protected by the ops sys.

If I want to protect our data structures against a competing software
company (who may have recently become good mates with our soon-not-to-
be-clients) - they can simply replace the isc4 gdb ( as the
administrator will let them ) and export all our data etc. etc.

Surely if some sort of link from the GDB to the isc4 was in place
this would stop this kind of activity ?

Thanks
