RFC 437           DATA RECONFIGURATION SERVICE AT UCSB         June 1973


   'TENEX-like' executive commands, commands are available for creating
   and storing forms by name, and for invoking the DRS compiler or
   interpreter.  Since both the compiler and the interpreter run
   asynchronously to the DRS/TSS, the user is notified when execution of
   his requests for compilations or interpreting are initiated and
   terminated.  In addition, a diagnostic message is supplied by the
   interpreter whenever it terminates execution of a form.

   When a user connects to DRS/TSS he is allocated an internal TTY
   number by which his terminal is identified.  When the user issues a
   command to invoke the compiler or interpreter, his TTY number and a
   user specified job name are used to uniquely identify the request.
   The jobname is thereafter used to refer to the request.  A Network
   host is specified by host name, or by host number preceded by #.  A
   socket number is specified as an integer, optionally preceded by a
   (decimal) to indicate the radix used.  Decimal is the default radix
   and positive the default sign.  A negative socket number is
   maintained in two's complement form.

   The following control characters are recognized by DRS.  Control A
   (SOH) or rubout (DEL) delete the last character, control V (SYN)
   deletes the last word, control W (ETB) deletes the last phrase, and
   control X (CAN) deletes the entire line.  Control D (EOT) displays
   the current word, control E (ENQ) displays the current phrase, and
   control F (ACK) displays the entire line.  Control Y (EM) displays
   the name of the current phrase.  Command accept is carriage return-
   line feed, or period.  A space will force recognition of the current
   word, and '?' will list the input(s) currently possible.

   The following sections describe the DRS/TSS command syntax. 
   denotes command accept, and brackets [] denote optional information.
   All literal information is enclosed in quotes ''.  Choose one
   alternative form items in parenthesized lists separated by |.
