FILE      -  post an existing file on the board. You can post any text file in
             this way.  Please limit the length of files posted however, so as
             to conserve space and improve the performance of the system.

EDIT      -  use the EDT editor  to create a message for posting on the board.
             The editor is invoked with word-wrap  and  other  word-processing
             enhancements. Use Control-Z and EXIT to leave the editor and post
             the message.

TOPIC     -  this is a privileged command available to users with a system UIC
             which allows them to add new topics to the bulletin board system.


DEARCHIVE -  also a privileged command  which allows .ARCHIVE files to be read
             back into the BB system.
