 Description:  A DOOR is an extension to the system.  A part of the
               system which is not built directly into the PCBoard Bulletin
               Board Software.

               Opening a DOOR takes you out of PCBoard and into another
               application.  Since there are dozens of DOOR applications
               available, you should check with your system operator for
               questions on which DOORs are operational and what they do.
