DFTP is the user program to store and retrieve  files  on  the
CCA  Datacomputer.   User files are compactified into a single
Datacomputer file, called the "<FILES>", and are stored on the
Ampex  terabit  mass  memory  in a similar data structure to a
DECtape.


DFTP is documented in DFTP.MRC[UP,DOC].  For more  information
or to report a bug, send mail to Bug-DFTP@MIT-AI.


DCSTAT is the program to print the status of the Datacomputer.
DC-203 (ie, the Datacomputer on the 203 socket at CCA) must be
both   "EXISTS"   and  "LISTENING"  in  order  to  access  the
Datacomputer.   DC-303 is the  older,  obsolete  Datacomputer.
If  DFTP behaves strangely, it is a good idea to run DCSTAT to
see if the Datacomputer is still up.
