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],  and a  primer
for new users is DFTP.PRI[1,REM].   For more information  on
DFTP, contact MRC or REM.  To report a problem in DFTP, 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.
