carriage return (null response). When the primary command source is other than an operator, each.
record is considered a response followed by a carriage return. Two examples of the general format
are:
COMMAND:
DEVICE:
PATHNAME:
PATHNAME:
SS
PR
.DIR.FILE
return
COMMAND: RPN
OPTION:
ON
The condensed format of the operator command begins with the COMMAND: prompt. All the
parameters for the command are entered following the command. The command and each
parameter are follo_wed by asterisks. If the final asterisk is omitted and additional parameters could
be
entered, the appropriate prompt for the next expected parameter is issued; i.e., the command
returns to the general format for the remainder of the command or until a parameter followed by an
asterisk is given. If a terininating asterisk is omitted by mistake, respond to the next prompt with a
carriage return. If an asterisk terminates a prompt line, no other input for this command will
be
accepted. For Command File mode and Intertask Message Queue mode, the condensed format is
more convenient to use. The condensed format uses only one record per command while the general
format uses one record per command and one record for each command parameter. Examples of the
condensed format are:
COMMAND: SS*PR*.DIR.FILE".DIR.FILEJ*
COMMAND: RPN*ON*
COMMAND: S*.DIR.FILE"
The terminating asterisk may be omitted when there are no more input parameters. as in the statistics
command: ST* ALL• or ST• ALL. The terminating asterisk must
be
used to terminate the condensed
format of the Send Data (S) and Send Data with Device Selection (SS) commands. For the Sand SS
commands, the terminating asterisk follows the last pathname input. The terminating asterisk must
be used to terminate the condensed format of the CALL command if the user wishes to specify
manual dial on a system configured with an ACU. In this case, the terminating asterisk follows the
command mnemonic CALL. The following are examples of the use of the terminating asterisk.
The following example shows the condensed format terminated with an asterisk indicating that
.DIR.FILE 1 is the last pathname.
COMMAND: S*.DIR.FILE".DIR.FILEJ*
An example of the condensed format without a terminating asterisk follows. The asterisk is not
necessary because there are no more input parameters.
COMMAND: RPRRL*JOO
The following example shows the condensed format with the terminating asterisk omitted by
mistake. The condensed format returns to the general format with its next prompt.
COMMAND: S*.DIR.FILE".DIR.f/LEJ
PATHNAME: return
