00100	DFTP is the user program to store and retrieve  files  on  the
00200	CCA  Datacomputer.   User files are compactified into a single
00300	Datacomputer file, called the "<FILES>", and are stored on the
00400	Ampex  terabit  mass  memory  in a similar data structure to a
00500	DECtape.  (Looks like a TENEX directory to the user.)
00600	
00700	DFTP is documented in DFTP.MRC[UP,DOC], and a primer  for  new
00800	users  is  DFTP.PRI[1,REM].    For  more  information on DFTP,
00900	contact MRC or REM.  To report a problem in DFTP, send mail to
01000	Bug-DFTP@MIT-AI.
01100	
01200	DCSTAT is the program to print the status of the Datacomputer.
01300	DC-203 (ie, the Datacomputer on the 203 socket at CCA) must be
01400	both   "EXISTS"   and  "LISTENING"  in  order  to  access  the
01500	Datacomputer.   DC-303 is the  older,  obsolete  Datacomputer.
01600	If  DFTP behaves strangely, it is a good idea to run DCSTAT to
01700	see if the Datacomputer is still up.
