DISPLAY
The J display shows the status of control points. The
current buffer of control statements for a job are
displayed, allowing you to anticipate future job
requirements. The next control statement to be processed
is intensified. The
J
display shows control point
parameters: control point number, job name, account block
SRU limit, accumulated SRUs (an approximation), CPU
status, contents of P register, central memory reference
address and field length, ECS reference address and field
length (if. any), and the equipment assigned to the control
point.

CENTRAL PROGRAMMABLE (K AND L)
DISPLAYS
Using the K or L display, a job at a control point can place
information on the console screen and receive information
from the keyboard. The information entered is not
executed by DSD, but is used by the job. Normally, these
displays are used for utility programs, such as REDEFINE
and FLAW (refer to section 6).
The job first issues a request message on the B display,
asking you to bring up the K or L display.
Type
K,n. or L,n.
n Control point number of the requesting job.
When the display is assigned to control point n, the type-in
(K. followed by data) is transferred to a specified area of
the job· field length when the carriage return terminates
the type-in. If more than 50 characters are entered as
data, the message
LINE TOO LONG.
appears on the screen. DSD does not accept the entry until
the data string is shortened.
Both the K and L displays are control point oriented. That
is, to page forward or backward through the display for
each control point, use the
+
and - keys, respectively. The
number of the control point appears at the top of the
display next to the display letter designator (for example,
K5).
