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 |.
