In the following example, an asterisk terminates the CALL command because the user's system is
equipped with an ACU, bµt the user wishes to dial the call manually. The asterisk prohibits
displaying the NUMBER: prompt.
COMMAND: CALL*
In the next example, no terminating asterisk is required since the system is not equipped with an
ACU (i.e., no other parameters are allowed). After issuing the CALL command, the operator
manually dials the call.
COMMAND:
CALL
Any operator response to a command or command parameter prompt that contains an' ampersand
(&)aborts that command. Another COMMAND: prompt is then displayed. An ampersand(&) is
accepted in the response to a PATHNAME: prompt of an S or SS command as long as it is enclosed
in angle brackets
(<
>).
In most cases an ampersand would not be used in the condensed format
since an incorrect response to the COMMAND: prompt can be corrected by backspacing and
retyping the response. The condensed format is included for comparison purposes in the examples
showing use of the ampersand to abort commands.
In the following example, the operator enters an ampersand to abort the RPRRL command.
General format:
COMMAND: RPRRL
LENGTH:
&.
COMMAND: next command
Condensed format:
COMMAND: RPRRL*&
COMMAND: next command
In the next example, the operator enters an ampersand to abort the SS command.
General format:
COMMAND: SS
DEVICE: PR
PATHNAME: &.
COMMAND: next command
Condensed format:
COMMAND: SS*PR*.DIR.FILE*&
COMMAND: next command
In the example which follows, the ampersand is part of a text string and does not abort the
command.
General format:
COMMAND: S
PATHNAME: <THIS IS TEXT&>
PATHNAME: return
Condensed format:
COMMAND: S*<THIS IS TEXT&>•
An example of the ampersand entered outside the text string, thus aborting the command, follows:
General format:
COMMAND: S
PATHNAME: <THIS IS TEXT>&
COMMAND: next command
Condensed format:
COMMAND; S*<THIS IS TEXT>*&
COMMAND: ne:·t command
