A control point number precedes the equipment number in
each entry if that piece of equipment is assigned to a
control point. An asterisk
(*)
instead of a period (.)
following the' channel number entry indicates that the
channel
is
down. The identifier code (un parameter)
provides a method of grouping peripheral devices when a.
si te has several units. Output from a job read in through a
card reader with identifier
xx
can only be directed to a
I
device with the same identifier. Changing the identifier
code via the ROUTE control statement or an LP DSD
command can direct program output to a special printer
(for example, for form control or multiple copy forms).
